Masquerain

You may sacrifice a creature named Surskit rather than pay this spells mana cost.
Flash, flying. Tribute 2
When Masquerain enters the battlefield, if
tribute wasn't paid, target player creates a green
enchantment token named Sticky Webs with
"Creatures you control without flying have last
-strike, lose and can't have or gain first strike." {2}, {t}: Target player's creatures get -X/-X until
end of turn, where X is half of Masquerain's
toughness rounded down.
