Rokuyuugou [6 fusion] archtype, it relates to level 6 or lower fusion monsters

[I Hate Snatch Steal]

 

When this card is Normal Summoned, you can add 1 "Rokuyuugou" monster from your Deck to your hand, except "Rokuyuugou Construct". Once per turn, if this card would be destroyed, you can shuffle 1 level 6 or lower fusion monster from your graveyard into the deck instead.

 

 

Once per turn: you can discard 1 card and tribute this card; special summon 1 level 6 or lower fusion monster from your extra deck. That monster gains 800 ATK and DEF. Also, once as long as it remains face-up it cannot be destroyed.

 

*updated to avoid issues with ryu-senshi's effect that negates spells that target it

 

 

Once per turn: you can discard 1 card; special summon 1 level 6 or lower fusion monster from your extra deck, it gains 1000 ATK and DEF. Also, it cannot be targeted or destroyed by opponent's effects this turn. This card cannot be used as synchro or xyz material the turn this effect is activated.

 

Please note that these cards do not fusion summon the monster: its just a generic special summon. Thus you cannot summon elemental HERO fusions because they require a fusion summon. You can however, summon a monster that has a condition like cyber twin dragon of requiring the listed material monsters for its fusion summon.
