I agree with @orannge in that seeing everyones personal memories and connections to Pokemon and specific cards is great to see shining through different collections
As with constructed Commander decks, the deck can include only cards allowed by the color identity of its commander
It might take a bit more patience, but sticking to retail pricing keeps my spending in check and ensures I'm collecting smart, not impulsively
Dreamstone Hedron proved to be too expensive for Constructed play, and Hedron Archive looks like it might be too
Its backside, Deluge of the Dead, is an enchantment that generates two 2/2 Zombies and can effectively eliminate cards out of graveyards to make more
From one pack you could theoretically pull 2x reverse holos and 1x Miraidon ex (either its Double Rare, Ultra Rare, or Hyper Rare Holo)
