BTW here is the card Lyall has:

[hider= Vile Arbitrator]

Vile Arbitrator
Level 6
DARK
Spellcaster

Effect: This card cannot be Normal summoned/Set. This card can only be special summoned by its own effect. When a card on the field is destroyed, you can special summon this card from your hand. This card gains 500 attack each time a card on the field is destroyed.
1500 attack/2200 defense

a bit of a ruling: This card does not gain 500 attack for the card destroyed for the summon.
