About this gameFull description from Steam
Deck-building meets monster catching in this turn-based roguelike. Recruit enemy cards to your party as you dive into the depths of the abyss. Will you kill them or will you tame them? In Decktamer, you'll encounter creatures that have adapted to their strange environment: the abyss. Rumor has it that anyone brave enough to reach the bottom of the giant crater will find great fortune. But watch out, as you dive deeper, the creatures only get more and more bizarre and dangerous... In this game, cards are not simply handed out to you, you have to tame your enemies to add them to your deck! But be careful, when one of your creature dies, the card is gone forever! Every turn, each one of your cards can use a move. Try to think about the optimal play to win your battle in this turn-based combat system! Will the turn plan out as you expected? The Abyss is filled with mutant creatures that possess abilities they shouldn't normally have. Use that to your advantage and transfer abilities from one creature to another to create unique and devastating combos! Only one question remains... Do you have what it takes to reach the heart of the abyss?
