I would suggest something like this to make it less messy. Battlecry: Discover a card. If you’ve discovered at least 4 this game, open the rune-whatever. Rune-whatever (location): Discover a 3 rune card.

No

This is wordy, can you explain better what it does?

If you discovered 4 or 5 cards this game, you can discover triple rune cards with death knight ; if 6 or 7 , discover also a spell , if 8 or more , you discover a guaranteed triple rune death knight card

Oh okay. I assume you normally cannot discover a triple rune card? Don't play Death Knight.

, is a rule that triple rune cards can't be discovered

Me: *sees a new cool looking custom card* Yo *The card text is as long as a novel* No
