The Epic Spell

Draw two cards, then discard a card at random.
For the rest of the game, change the texts of each
card you own with mana value X by replacing all instances of "can't" with "can", where X is the discarded card's mana value.
Epic (For the rest of the game, you can't cast spells.
At the beginning of each of your upkeeps, copy this
spell except for its epic ability.)
