Starving Venom Invasion

You can use this Skill’s second and third effects once per Duel if your Extra Deck contains "Starving Venom Fusion Dragon". 1: You can only Normal or Special Summon "Predaplant" monsters (excluding Special Summons from the Extra Deck). 2: Reveal 2 cards from your hand, that are "Predap" cards, "Polymerization” Spell Cards, and/or "Fusion" Spell Cards, then add 1 "Polymerization" from outside of your Deck and 1 "Predap" card from your Deck or Graveyard to your hand. 3: If only your opponent controls a monster, place 1 Predator Counter on a face-up monster your opponent controls, and if you do, any of those monsters that are Level 2 or higher become Level 1 as long as they have a Predator Counter.
