It even skirts the legend rule, so no worries there
Theres fairly good value in Endless Punishment with good reprints and desirable new cards, and a powerful commander, as long as you know youll probably be public enemy number 1
I would say that is less "build out of the box", less budget-friendly, & probably needs a little more card-draw fluff since the commander does not do that on his own
You can print a single card if you want, and larger orders get better per-card pricing
Just about the only real place for Thurid is in one of those changeling-heavy decks that leverage the overpowered abilities of commanders like this, abilities which are balanced out by the fact that the type theyre supporting sucks really bad
Prowess with haste is awfully good, and just when you run out of gas, you can drop this and flip it for a total of 4 mana in the right deck, and draw three cards
