I was thinking about putting both abilities on the stack. Do you have to discard the cards you get from the first ability. It's mostly me trying to break cheap cards
Yes, that would work. Everything before the ":" is the cost, the result (what happens when you resolve it) is on the right. So if you activated one
bomat courier's ability, you would discard your hand, the ability would then be placed on the stack.
Before passing priority / resolving the ability, you can activate the second
bomat courier's ability, discarding your hand (nothing, since you discarded it before you drew the cards under the first Bomat).
When all this resolves, You would then place the second bomat's cards into your hand, then place the first one's cards into your hand.
Nifty stuff, really.
