Cards like this are fine enough filler when you do have tutors and things but they are pretty essential, and in good number, when you don't
Im a certified combat enjoyer, so I love basically every card that lets you do even more combat
This one will cost you $296 on TCGPlayer
I like the card well enough, but its definitely pulling you in a different direction than what this precons trying to do, so Im pretty firmly on Team Mirko here
Black-Blue-Green are the Sultai, who revere their dead and trawl through the graveyard, all the while persisting and controlling the board Green Blue Red are the Temur, all about casting big powerful creatures, generating the mana to do so, and annihilating the opposition in a rain of dragonfire
And yeah, Jace defined an era of Magic and still shows up in Eternal formats today
