At his most powerful, you can summon Elemental HERO Grandmerge using 2 Elemental HERO Neos as material giving Grandmerge an attack of 4,200. Elemental HERO Neos Alius can be used as material so long as he has not been Gemini Summoned.
Here are some of the monsters you can Special Summon with Elemental HERO Grandmerge's effect. Some monsters, like Elemental HERO Great Tornado, will not trigger their effects because they require Fusion Summoning. However some monsters, like Elemental HERO Necroid Shaman, will trigger their effect because they only require Special Summoning.
Reduce the level of the monster you Special Summoned with Elemental HERO Grandmerge's effect to ease its attack restriction.
