Monster Draft : Merge Runner

Review by eFreeware

Monster Draft is a free card battler from Oreon Studios, released in April 2022 and rated Teen. You gather monsters as cards, merge duplicates into stronger versions, and send a chosen team into turn-based battles against other creatures and oversized bosses. The hook is the combination of collecting and merging: rather than chasing a single rare pull, you build strength by combining what you already have.

That combination is the main reason to consider it. The game has drawn a large audience, with more than 50 million installs and a 4.8 average across 182,525 ratings, which suggests the loop keeps people coming back. It is supported by ads and offers in-app purchases, so it sits firmly in the free-to-play space rather than being a one-off paid title.

What appeals to me from the developer's outline is the breadth of the roster. The app offers over 100 monsters, each with its own abilities, plus superheroes and animals that can join your ranks. That variety gives the deck-building side something to work with, because a card game lives or dies on whether the pieces feel different from one another.

How a run actually works

The core loop starts with collecting. You pick up monsters through quests and other rewards, then train and upgrade them over time. Each creature has its own set of abilities, and the developer frames battles as strategic rather than automatic: you choose which monsters to field and when to use what they bring. Picking the strongest monsters and planning your moves is what carries you through a fight.

Merging sits alongside that. Combining monsters is how you reach the Gold and Diamond forms, which the developer describes as evolved versions with far more power. This gives duplicates a purpose beyond clutter. In most collection games, spare copies are filler; here they feed directly into the upgrade path, which is a tidier design than it first appears.

The Card Factory is the third piece. It lets you produce the cards you need rather than waiting on random drops, which matters in a game where deck composition decides matches. Between the factory, merging and quest rewards, there are several routes to the same goal of a stronger team, and that redundancy is usually what keeps a collection game from stalling.

Quests, eggs and the long climb

Progression runs through quests. You head out to find monster eggs scattered around the world, and each one can yield a new companion, including rare and legendary creatures. Eggs are the discovery layer: you know roughly what you are hunting for, but not exactly what will hatch, which gives the collection side a bit of suspense.

Boss fights sit at the other end. The developer describes colossal bosses and challenging quests, so the game is built around a difficulty curve that pushes you to keep upgrading rather than coasting on early pulls. Gold and Diamond evolutions read as the answer to that curve, since they are what you reach for when a standard team stops being enough.

The roster extends beyond monsters. Superheroes and animals are also part of the collection, with King Kong, Godzilla and other giant creatures among the draws. That mix gives the theme a looser, more playful feel than a straight creature-collector, though it does mean the world is a patchwork of influences rather than one coherent setting.

What the free version involves

Monster Draft is free to download and supported by ads, and it offers in-app purchases. This is a game built to be played over a long stretch, with optional spending available along the way.

Monsters are earned through quests and eggs, and specific cards can be crafted through the Card Factory, which are the kinds of systems that give free players a route forward.

The content rating is Teen, which fits the monster-battling theme. The most recent update, from September 2026, brought bug fixes and performance improvements, so the game is still being maintained rather than left as it launched.

The player this fits

This is a game for people who enjoy collecting as much as competing. If the pleasure of a card game for you is in the catalog, in filling gaps, in evolving a favorite into its final form, the merging and egg-hunting systems are aimed at exactly that instinct. The strategic battle layer gives those collections somewhere to go.

It also suits players who like a clear upgrade path. Gold and Diamond forms, the Card Factory and quest rewards all point in one direction, and there is little ambiguity about what to do next. That kind of structure works well for shorter sessions where you want to make visible progress rather than learn a new system every time.

The looser theme is a factor too. Superheroes, animals and giant monsters sharing a roster gives the game a broad, almost toy-box quality. If you prefer a tightly consistent world, that mix may feel scattershot; if you just want a wide range of creatures to collect and combine, it works in your favor.

A free-to-play collector with a merging hook

Monster Draft is a well-established free card battler with a big audience behind it, and the merging mechanic gives it a clearer identity than most games in the genre. Collecting monsters, combining them into Gold and Diamond forms, and crafting the cards you need through the Card Factory form a loop that rewards patience and planning rather than luck alone.

The caveats are the usual ones for the format. The quest-and-boss structure implies a long grind between milestones. The theme is a grab bag of monsters, superheroes and animals, which is either part of the charm or a distraction depending on your taste.

If you like collection games with an evolution system and turn-based battles, this is an easy one to try, since it costs nothing to start. If you want a tight, single-themed strategy game, the shape of it will not be what you are after.
