Since I realised about halfway through today that Armors were a way better fit for Keitaro than Psychic, that's now his deck. Also, because Armors are lacking a bit of punch, have the first custom card in the RP:

[b]Gravitational Barrier[/b]
Type: Field Spell
Effect: When an Armor monster you control declares an attack on an opponent's monster, you can have the attacking monster gain 200 ATK for each face-up card on the field.

These will be located in the second post of the thread (excluding the 0th post)
