Whenever Water Weird deals combat damage to a player, put a +1/+1 counter on Water Weird if the top card of your library is a nonland card. Otherwise, you may mill a card.
Each player sacrifices all artifacts, enchantments, and nonbasic lands they control. For each land sacrificed this way, its controller may search their library for a basic land card and put it onto the battlefield tapped. Then each player who searched their library this way shuffles.
Wayfaring Temple's power and toughness are each equal to the number of creatures you control. Whenever Wayfaring Temple deals combat damage to a player, populate.
