This terrifying enchantment card, Call the Spirit Dragons is an alternate win condition that seems very easy to set up, and is extremely powerful even if it never goes off
It requires you to play basic lands or domain mana to come down untapped, but Archway of Innovation dishing out improvise is insane with the number of artifact tokens out there
Consulate Surveillance doesn't target and can affect any source, so it can stop damage from a hexproof or protection creature, or a burn spell aimed directly at you
The artifact chosen to be sacrificed is still on the battlefield up through the time that you activate mana abilities
: Until end of turn, this land becomes a 3/2 blue and black Elemental creature
Running for around $130 at market on TCGplayer right now, this is still a hot card to come by, even if it just misses out on a top ten ranking by value
