Mitsuhiro Arita (modern) the original Base Set Charizard illustrator, and his modern Pokemon work including occasional SAR contributions carries significant premium for nostalgia alone
Prismatic Ending If Commander decks don't care much about Leyline Binding, they haven't even heard about Prismatic Ending but in 60-cards formats that can play it, and Modern above all (where Swords to Plowshares isn't legal), you could argue that this white sorcery is so good it actually killed Path to Exile
The PSA 10 Pikachu Illustrator has arrived on @LiquidMarketpl
Im surprised that a card like Geralf, Visionary Stitcher, which does the same for zombies decks, doesnt see more play for this reason
(For example, one could play Lugia to beat Urshifu but that deck is unfavored against Miraidon, Charizard, and Gardevoir, so its hard to justify bringing it to any major event.) The main threat to the deck is Mew VMAX, which has a decent matchup spread outside of Urshifu
