Infinite storm countInfinite untap of some creatures you controlInfinite power and toughness for certain creatures until end of turn
How it works
Cast Banishing Knack by paying , targeting a Bird, Rat, Otter and/or Frog you control that does not have summoning sickness.
Valley Floodcaller triggers, giving Birds, Otters, Frogs and Rats you control +1/+1 until end of turn and untapping them.
Resolve Banishing Knack.
Cast Basalt Monolith by paying its mana cost.
Valley Floodcaller triggers, giving Birds, Otters, Frogs and Rats you control +1/+1 until end of turn and untapping them.
Activate Basalt Monolith's first ability by tapping it, adding CCC.
Activate the creature targeted by Banishing Knack by tapping it, returning Basalt Monolith from the battlefield to your hand.
Repeat from step 4.
This delightfully peculiar loop turns a humble creature into a persistent bounce engine by granting them an activated ability through Banishing Knack. Once the creature is thus empowered, you cast Basalt Monolith, which immediately triggers Valley Floodcaller to untap your eligible creatures and grow their power and toughness. You can then tap the Monolith for mana, use your Knack-enchanted creature to bounce it right back to your hand, and repeat the process indefinitely for an unbounded storm count.
