Smash away

Reckoner Bankbuster Banned during the latter half of its tenure in Standard, Reckoner Bankbuster is a colorless value engine that can go in any deck thats not just flat-out aggro

If this card is flipped face-up: During the End Phase of this turn, change as many face-up monsters on the field as possible to face-down Defense Position, then you can Special Summon 1 "Ghostrick" monster from your Deck in face-down Defense Position, whose Level is less than or equal to the number of monsters flipped face-down by this effect

It makes your Voltron creature much more annoying to get rid of as it recurs itself at the end of the turn

However, Rainbow Kuriboh will be banished once it leaves the field after activating this effect
