It deals 70 damage off two Lightning energies, which isn't bad, and its Counterattack ability, which deals 20 damage to any active Pokemon that damages it, is nifty, but the fact that it's a stage two Pokemon slows things down
Not only that, this card has a good amount of willpower and lore-generating capability too, since each quest gets you three lore, so it can tank some damage and still help you win the game.
Note: Im excluding Dockside Extortionist, as that $90 card has extorted enough money from people
Tibalt, Cosmic Impostor creates an emblem that counts everything the planeswalker exiles, even if its been removed
Feels like a card for Commanders like Saheeli, the Suns Brilliance, who already make token artifacts in the Command Zone
Magneton Magnetons holofoil card is often underrated, but its striking design and rarity make it a sleeper hit among Base Set collectors
