C Common Neos Fusion X SPELL Special Summon 1 Fusion Monster from your Extra Deck that lists exactly 2 monsters as material, including "Elemental HERO Neos", by sending those monsters from your hand, Deck, or field, ignoring its Summoning conditions

This means that Chandra, Fire of Kaladesh would deal 2 damage because she is a 2/2

Normally you need legendary creatures with the partner ability to use two for your commander, but Commander Masters has a special rule that lets you use two monocolored, or even creatures with no color identity as if they had partner
