Magnum the Reliever →Used Deck

Since one side of the fusion material requires a "monster that was Special Summoned from the EX Deck", the other side is "a monster in your hand", so naturally it is adjusted so that "Super Polymerization" cannot be used.
That's why you need to fusion summon this monster with your own monster as a fusion material with "Fusion" / "Fusion" Spell, taking into account the fact that you use two of your own effects, but from the EX Deck to Special Summoned monsters also need to be on the field as fusion materials, so how to secure them is an issue when using this card.
An appropriate Link 1 monster is suitable as an EX monster, but 《Instant Fusion》, 《Ready Fusion》, and 《Fusion Armament》, which are “Fusion” Spell cards and can prepare monsters Special Summoned from the EX Deck, are better than using this card. It will be a powerful card.
Surprisingly, "Fusion Sage", which itself is a "Fusion" Spell card and can bring in "Polymerization" to fuse summon this monster with its effect, can perform 1 and 2 effects of this card with 1 card. It's powerful in that it's worth two "Fusion" spell cards to use each once.
It also has effects that are not bad, such as Recycle & 1 Draw, and a target removal effect that can be used to interfere with the opponent's turn by reacting to the activation of effects other than your own.

It's lighter than I thought because it can use Link as a material, but it's up to Deck whether he wants to make this card that's just convenient to have.
