Mega Darkrai ex 48/84 Double Rare The one you actually sleeve and play
If Shining Shoal was cast in advance with X = 6 and Abyssal Persecutor was chosen as a source of the damage, all this damage will be redirected
it stabilizes the board the moment you cast it by exiling a problematic permanent
It essentially converts extra draws into +1/+1 counters, which answers the age-old question: I've drawn a ton of cards, now how do I win? The cantripping nature of this blue enchantment also means it's never a dead card, even if you're not completely going off with it
Enchantment decks often have a handful of cards thanks to all of its draw triggers, allowing you to always have an answer or discard fodder
It's slightly bothersome that the power and toughness box is on the left side of the card, but it's visible and fits the geometry of the art well enough.
