Jadelight Ranger | Creature | Merfolk Scout Ranger | When Jadelight Ranger enters the battlefield, it explores, then it explores again. (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. Then repeat this process.) | Jason Rainville

Wayward Swordtooth | Creature | Dinosaur | Ascend (If you control ten or more permanents, you get the city's blessing for the rest of the game.) You may play an additional land on each of your turns. Wayward Swordtooth can't attack or block unless you have the city's blessing. | Chris Rahn
