Common Complexity Let's walk through each of the three types of complexity
Not only does Hieratic Seal Of The Heavenly Spheres allow you to bounce back any card your opponent controls, but it can tribute itself for this effect
If this card is Normal or Special Summoned: You can Special Summon 1 "Gishki" monster from your Deck, except "Gishki Grimness", also you can only declare attacks with Ritual Monsters until the end of this turn, except with Ritual Monsters
This should be a solid deck provided there's a strong pool of equipment and a selection of creatures that'll permit players to go a little wide while building up Cloud to his full opponent-smashing potential
Forbidden Cards Forbidden Painful Choice X SPELL Select 5 cards from your Deck and show them to your opponent
C Common Shield Warrior X EARTH Level 3 [ WarriorEffect ] ATK 800 DEF 1600 During damage calculation, in either player's turn: You can banish this card from your Graveyard
