The reason why Blossoming Tortoise is so high on this list, however, is that its likely to appear in Pioneer extensively at least for a period of time
Many protection spells, such as Akroma's Will and Heroic Reinforcements, only provide opposing boards with indestructibility, so exile-based wraths safely ignore them
While theres a lot of synergy here, the cards are mostly strong independently, and the deck is designed to play a fair, interactive game that just happens to be able to gain infinite life with Urza and the Thopter Foundry / Sword of the Meek Combo, but mostly Urza, Oko, and Emry are all amazing standalone cards that require fairly different answers
But Greg, Ariel is a Super Rare and Gaston is an Uncommon, so it should be better. While the rarity of a card certainly can play a part in its value on the table, its not always 100% the case
No one can try to destroy the creature you sacrificed to prevent you from casting this spell
Urtet isn't super powerful, and you can definitely get blown out by an overloaded Vandalblast, but I'm really happy that we now have a viable Five-Color Myr commander in the format
