Hyper Cannon Activation

You can use this Skill's second and third effects once per Duel if your Extra Deck contains "XYZ-Hyper Dragon Cannon". 1: At the beginning of the Duel, add 3 LIGHT Machine Fusion Monsters to your Extra Deck and banish 3 monsters from outside of your Deck. During this Duel, you can only Normal or Special Summon "Obelisk the Tormentor", "X-Cross Cannon", or LIGHT Machine Normal or Union monsters (excluding Special Summons from the Extra Deck). 2: During your main phase, play 1 LIGHT Machine Union monster from your hand, then add 1 Level 4 LIGHT Machine monster from your Deck to your hand. 3: If you control a Level 8 or 9 LIGHT Machine Fusion Monster, or if your opponent controls a monster, set 1 Spell/Trap Card that mentions "Union monster" in its text from your Deck to your field. (This card can be activated the same turn.)
