March of Swirling Mist

Menace When this Vehicle enters, it deals damage equal to twice the number of Vehicles you control to target creature or planeswalker an opponent controls. Crew 4

Ninjutsu 3G (3G, Return an unblocked attacker you control to hand: Put this card onto the battlefield from your hand tapped and attacking.) Whenever this creature deals combat damage to a player, return target permanent card from your graveyard to your hand.

If a creature attacking causes a triggered ability of a permanent you control to trigger, that ability triggers an additional time.

Other enchantment creatures you control get +1/+1. G, T: Copy target activated or triggered ability you control from an enchantment source. You may choose new targets for the copy. (Mana abilities can't be targeted.)

R: Creatures you control gain haste until end of turn. 3RR: Create a 5/5 red Dragon Spirit creature token with flying. Activate only if you control an attacking modified creature. (Equipment, Auras you control, and counters are modifications.)

Double strike Equipped creature has double strike. Reconfigure 2 (2: Attach to target creature you control; or unattach from a creature. Reconfigure only as a sorcery. While attached, this isn't a creature.)

Create X 2/2 white Samurai creature tokens with vigilance. They gain menace and haste until end of turn. Each opponent creates X minus one 2/2 white Samurai creature tokens with vigilance.

The "legend rule" doesn't apply to permanents you control. Each legendary creature you control gets +1/+1. Each nontoken creature you control gets +1/+1 for each other creature you control with the same name as that creature.
