mtg story cards Lorwyn Eclipsed Magic the Gathering (mtg): ELD:

To me, designing Theros Beyond Death has been like coming home

So itll often just be a reanimator spell for 4 mana at instant speed when you block with a token

When in play, a huge number of Planeswalkers can activate their ultimate ability from the moment they hit the board

That being said, I would actually ban [Card]Saheeli Rai[/Card] over [Card]Felidar Guardian[/Card] as I think the cat could see play without Saheeli and I dont think the statement is the same vice versa

A heuristic I have found useful for identifying cards fundamental to the functioning of a deck is this: does your deck mulligan a high percentage of hands that do not contain this card or this class of cards
