I think this effect is a bit too narrow for serious consideration unless you really need a way to tutor your Walking Ballista
Ancestral Blade is one of the first equipment without a mechanic that specifically brought a creature into play with it
Holding cards for coordinated plays later, setting up powerful Songs, knowing when to sacrifice characters to banish an opponent, anticipating the play your opponent is setting up based on their deck composition
While its disappointing to see the best Warhammer faction not get its own Commander deck (stupid Marines soaking up the spotlight), fans will no doubt appreciate more cheeky references
Regardless of the game youre playing, Cyclonic Rift always gives you asymmetric value, since it simply cant hit your permanents (without someone flashing in Dualcaster Mage or the like)
Cascade is a powerful effect for sure every time you cast this elf berserker, it brings an extra card with it
