The most important aspect is to ensure your win condition needs cards in the graveyard
Five mana for a rock that produces WUBRG is pretty cheap, and youd end up paying more for it to enter untapped (though how much more, when Chromatic Orrery is seven mana, Im not sure)
Id probably even go for a Dragon Shield Matte or Dual Matte instead of the Ultra Pro Eclipse, just because the taller sleeves might fill out the pockets a little better - though even then those pockets seem like theyll be pretty roomy vertically
For the cost of one blue and one generic, you can tap and remove twelve time counters to shuffle your graveyard and hand back into your library, then draw seven cards
The discounts for preconstructed decks in the store will now be based on the cards in your collection with the same name as the cards in the deck
Finally, add Trainer cards, Supporter cards, and Stadium cards to fnish the deck
