Bug fixes to primitives

Keruga, the Macrosage: other permanets so it shouldn't count itself
Mirkwood Spider: extra )
Meria, Scholar of Antiquity: using macro for __PLAY_TOP_FROM_EXILE__
Quarrel's End: was missing the draw 2
Leonin Bladetrap: was missing the {2} activation cost
Strixhaven Stadium: mana ability was not adding a point counter
Gorgon Recluse: should only kill nonblack with their ability
Mass Diminish: should be until your next turn
