Shruit, Brio, Unicore, Prep of Rites, Nekroz cycle Shruit makes the high level Nekroz with no dedication and gives a free search, it can stay at 1 Unicore invalidates the extra deck and gets a free search off scope, it too can stay at 1 Cycle makes very easy Djinn locks with claus Prep is a double searcher that can recycle cycle Nekroz of Brio is best option to help Nekroz out a bit Dragon Ravine (from limited) - Help Felgrand, Blue Eyes don't run it Ring of Destruction (from limited) - the burn damage capabilities doesn't offset the weakness that it targets and destroys
The 200-card core of Planar Cube contains plenty of great ways to maximize your mana and answer your opponents' threats but few ways to win the game
That allows you to cast those spells more easily, potentially allowing you to cast extra instants and sorceries each turn, pumping up Stormcatch Mentor's power and toughness even more
My advice is this
[2] If a monster is banished, face-up, while this card is in the GY: You can banish this card, then target 1 "Invoked" monster in your banishment
