Even starter deck cards can hold value
I know several of us here have tried to make it work and it didn't, so I see it as a trap, personally
As you might foresee, this can lead to some utterly bonkers interactions: Living Lands paired with this means no one can tap for mana any longer, as a mana ability is still an ability
After drafting the set for over six hours during an early Arena streamer event, I suspect that Avatar will go down as one of the best-received Universes Beyond crossovers
Undying returns your creatures to play untapped, so if youre able to hold this until you have a sizable board you can unleash a surprise all-in attack to kill one opponent and then reset your board (and triggers!) with whatever sacrifice outlet you have around
I cant see the harm in sitting on a brick of these now and letting time run its course
