If this card is Normal or Special Summoned: You can add 1 "Polymerization" from your Deck to your hand. During your Main Phase: You can activate this effect; you cannot Special Summon monsters for the rest of this turn, except Fusion Monsters, also send 1 "Elemental HERO" monster from your Deck to the Graveyard, except "Elemental HERO Blazeman", and if you do, this card's Attribute, ATK, and DEF each become the same as the monster sent to the Graveyard, until the end of this turn. You can only use 1 "Elemental HERO Blazeman" effect per turn, and only once that turn.
Once I got Draw Sense: Fire on Jaden I knew I could make an E-Hero deck work, definitely my favorite deck to play with now. Focus is on cards with discarding effects that sync well like Fusion Recycling Plant and Cyber Gymnast; I can also fuse Neos Knight and bring Neos back with Oversoul/Birthright, or toss Necroshade for an easy summon. It won't consistently beat all the phoenix and ancient gear decks out there but it's super fun.
this card is easily the beet hero in the game it draws your polymerization just like fusion sage it thins your deck every turn just like gozuki then with cards like e hero necroshade and o-oversoul allow you to use your graveyard as a resource and it gains its stats insane card!! it sucks that this card is pretty much carrying e heros rirht now and i hope that the archetype in general gets better.
if you summon it and activate the Polymerization effect, then you have to wait until the next turn to active its second effect. If you summon but do not activate the Poly effect, then you can do the send an E-hero to the GY thing.
