Magic The Gathering Cards of types 'Lhurgoyf' and 'artifact'

Whenever a creature you control attacks alone, it gets +X/+X until end of turn, where X is the number of card types among cards in all graveyards. Lhurgoyf creatures you control have trample.

Subgoyf's power and toughness are each equal to the number of different subtypes other than creature types among cards in all graveyards and its toughness is equal to that number plus 1. (Subtypes include but are absolutely not limited to: Plains, Equipment, Aura, Arcane, Jace, Curse, Urza's, Ulamog's, etc.)
