By sending a card from your hand to the Graveyard, Naturia Gaiastrio can negate the activation of any card that targets a card on the field
But that wont work if theyre used as equip cards, though
Special Summon up to 3 "Ice Barrier Tokens" (Aqua/WATER/Level 1/ATK 0/DEF 0), and if you do, increase this card's Level by that number, also you cannot Special Summon from the Extra Deck for the rest of this turn, except WATER Synchro Monsters
The only difference between Bracket 4 and cEDH is that you arent tuning your decks for an expected metagame
(8/25/2017) If a token is phased out, it will phase in as your next untap step begins
Notably, Worldslayer includes lands in its destruction effect
