One of the central tenants of my TCG is having a "hand-less", open deck format where all cards are accessible for the entire game. The idea is that your deck functions more as a spell book and you memorize spells That are available to cast the following turn (think D&D). In addition, cast spells return to your deck after their cooldown, allowing for reuse (but may be removed from the game via effects and abilities).
Randomness comes during casting via dice rolls instead of through unpredictable card draws. Number of dice, available memorization slots etc increase over the course of the game.
What ramifications do you see with this? Any potential issues I should look at addressing? Any thought and feedback would be greatly appreciated! Thanks!
