Combos Utilizing Worldslayer

equip artist with worldslayer. remove fade counters from tide to remove your land from game (til end of turn). before worldslayer's removes all permanents, use artist ability to return it to your hand

When you smack a player, have lots of the Symbiotic and Penumbra creatures out, or Summoner's Egg, and everything will die that isn't regenerated/indestructible, leaving you with a board of creatures!

float mana for caller. equip anurid & attack. before worldslayer's resolves, discard 2 cards & remove anurid from play. player caller. put 2/2 tokens into play for each creature you lost to worldslaye

play world slayer and pattern of rebrith and attack and search for big bad creatures

after creature equipped with worldslayer damages your opponent, cast wail to regenerate all your creatures

duh!!!!!!!!!!!!!!

ALOT of life if you can get the mana for the latter after worldslayer
