In my opinion the key buff Slivers are: Sinew Sliver, Sedge Sliver, Predatory Sliver, Muscle Sliver, Megantic Sliver, Cleaving Sliver, and Bonescythe Sliver
Artifact Color tag templates(None) Lucky Clover Whenever you cast an Adventure instant or sorcery spell, copy it
Perhaps more critically for the Doctor Who cards, however, is the interesting trend of other cards giving other cards Suspend
But thats not the case with this deck
This deck is weak to countermagic and similar interaction Game 1, so it makes a lot of sense to transform into the older creature/planeswalker plan, and I believe Glorybringer to be a great way to facilitate playing fair. Creatures (17) 2 Ayli, Eternal Pilgrim 2 Archangel Avacyn 4 Thraben Inspector 2 Thalia, Heretic Cathar 3 Sram, Senior Edificer 4 Walking Ballista Planeswalkers (4) Lands (24) Spells (15) Probably my most boring deck today, but I think it showcases a valuable lesson
