16 damage Naya combo

Probably the best Naya combo that can be arranged in early game, even in the fourth turn.

Turn 1: Forest + Wild Nacatl
Turn 2: Mountain + Mogg Fanatic
Turn 3: Plains + Woolly Thoctar
Turn 4: Forest + Attack with Woolly Thoctar + Giant Growth + Soul's fire.

Cool Naya/Bant Combo

How to deal 5 damage on the second turn? Well, mostly it depends on your luck, but let's give it a try?

Turn 1: Plains + Akrasan Squire
Turn 2: Forest

You attack with the first Akrasan Squire and boost it with Resounding Roar. That's 3, plus 2 from the exalted.

Hopefully, you'll get the right cards and the opponent will take the damage.
