Maybe were supposed to look at some cycling stuff, but losing even more tempo just doesnt resonate with me on this one
If a card that has mutate also has flash, like Pouncing Shoreshark, you can flash it in for its mutate cost since its an alternate casting cost rather than an activated ability
If they let the green ramp player cast whatever they want or use all their mana sinks as they please then they have no hope
