- Random environment generation (absolutely)
- Permadeath (sure)
- Turn-based (you betcha)
- Grid-based (for varying definitions of grid, I'll allow it)
- All actions take place in the same mode (the mode is cards)
- Several solutions to common goals (sometimes you can vary which card goes on which)
- Resource management (cards)
- Hack'n'slash (it's player vs world with no monster-monster relations)
