Nadu, Winged Wisdom + Scute Swarm + Puresteel Paladin

Nadu, Winged Wisdom

Scute Swarm

Puresteel Paladin

How it works

1. Activate an Equipment's equip ability by paying 0, targeting a creature you control.
2. The creature triggers, causing you to reveal the top card of your library and put it onto the battlefield if it's a land card, or put it into your hand otherwise.
3. If a land was put onto the battlefield, each Scute Swarm you control triggers, creating either that many 1/1 Insect creature tokens or that many token copies of Scute Swarm.
4. Resolve the equip ability from step 1.
5. Repeat as able.
