Your opponent plays time walk, you counter it
Slot 13 is a non-foil wildcard, which can be any card from the set
In a format where words like redundancy or synergy get thrown around a lot, its quite weird that this one isnt on people's minds when building for hand knowledge
(You may cast this card from your graveyard for its escape cost.) To determine the total cost of a spell, start with the mana cost or alternative cost you're paying (such as an escape cost), add any cost increases, then apply any cost reductions
For now, this is a paltry dinosaur payoff that you can certainly run in the 99, but not one you're ever putting in the command zone outside of Pauper Commander
Since multiple orders are combined and shipped in a single package it appears that the tracker will not update to arrived until PSA processes the package and scans your individual submission
