Currently, the D23 Promo version of Captain Hook is valued at about $1,300 on TCGPlayer
I feel like its teaching me the skills I need to learn just by opening up packs of cards and sorting them out, which is not something Im used to with other card games
When your opponent activates Blocker, if either of you has 0 Life cards, you win the game
Shadows cards best ability is Chaos Control, which has the potential to give the Split Second ability to all players who cast spells if the mana spent was from an artifact
6 Prophet Of Kruphix Two cards that see a great deal of play in the Commander format are Vedalken Orrery that allows its controller to cast all of their spells at instant speed, and Seedborn Muse, a creature that untaps each of its controllers permanents during each other player's upkeep
If its almost good enough for that, itll be a slam dunk in a deck built around energy
