Ill be the first to admit that I dont love the concept and aesthetic of Aetherdrift, but there are still plenty of super cool cards in the set
If you mean 'challenging' other characters, or glimmers, in play Steel and Ruby are good at challenging and can get benefits for banishing opposing characters during challenges
Subsequently, its rather hard to judge the full strength of the mechanic just yet
As such, Ive recruited Cryptic
Its very strong to cast Taigam, Master Opportunist, then follow it up with something like a Shock and a Preordain, and this card should see plenty of play in blue-based tempo decks
Potentially, this spike may continue to climb in the coming days and weeks, since there are only 33 liftings left on TCGplayer
