The GNAR! to new wall combo is pretty popular, but it does deserve mention. Although it doesn't exactly work all that well with Trundle's pillar... Anyway, he mentioned the buddy bomb thing at the end. It works best with Zilean, but Tristana can also get in on the action, assuming the minion doesn't die before they get rocketed into the enemy team. Cassiopeia's E does indeed synergize with Teemo and Singed's respective poisons, but not with Gangplank, the Gromp Smite buff, or Twitch. The first two simply don't count, and Twitch's passive isn't shown as a poison effect because of its unique mechanics. It stacks, it does true damage, and it has a unique particle effect. And no, Ashe/Anivia doesn't work. Anivia's E sadly only checks for her own slows. Makes sense, since if it read any icy slow people could just build a Mallet or Rylai's for free synergy.
