Sadly, I don't see any way of nerfing this deck without killing it off entirely
Like most Pokmon cards, the value of Sableye depends on a few consistent factors: its rarity, the printing and finish (regular or foil), its physical condition, and the set it was printed in (HSUndaunted)
But only when you shoot foes and only if the damage is fewer
Creatures (9) Lands (21) Spells (30) Creatures (12) Lands (21) Spells (27) Creatures (16) Lands (20) 20 Island Spells (24) 4 Opt 2 Spell Pierce 2 Entrancing Melody 1 Chart a Course 3 Dive Down 4 Curious Obsession 1 Blink of an Eye 4 Wizard's Retort 1 Quench 2 Essence Capture Sideboard I think theres a good lesson to be learned comparing Thought Erasure and Dive Down
Players should also consider other board-wide creature-buffing effects like Imperious Perfect, Maja, Bretagard Protector and Elesh Norn, Grand Cenobite, as these give players more options to give +1/+1 counters to their tokens and small creatures
While Enduring Vitality is a great card on its own for its low cost and reanimating ability, it grant only creature tokens the ability to tap for mana
