When Limited Resources enters the battlefield, each player chooses five lands they control and sacrifices the rest. Players can't play lands as long as ten or more lands are on the battlefield.
At the beginning of each player's upkeep, that player chooses target player who controls more lands than they do and is their opponent. The first player may search their library for a basic land card, put that card onto the battlefield, then shuffle their library.
Defender At end of combat, exile all creatures blocked by Wall of Nets. When Wall of Nets leaves the battlefield, return all cards exiled with Wall of Nets to the battlefield under their owners' control.
Flying When Welkin Hawk dies, you may search your library for a card named Welkin Hawk, reveal that card, put it into your hand, then shuffle your library.
