Flying
Whenever Taifeng Cartographer attacks, add one mana of any color. Until end of turn, you don't lose this mana as steps and phases end.

Whenever Tortle Veteran or another Turtle you control enters, that creature explores. (Reveal the top card of your library. Put that card into your hand if it's a land. Otherwise, put a +1/+1 counter on this creature, then put the card back or put it into your graveyard.)

Erratic, erratic, erratic (When this creature dies, reveal the top four cards of your library. Put a creature card that costs less than this revealed this way onto the battlefield and the rest on the bottom of your library in any order. Repeat this process twice.)

Copy target spell twice. You may choose new targets for the copies. (A copy of a permanent spell enters as a token.)
