Both effects work with each other, and in fact, you will most likely need to play Present Arms first before the creature's baseline effect can do anything
While this might be changing in the future, for now, this essentially adds $19.99 to the cost of building a deck (since all or nearly all tier decks have at least some adventure cards), raising the average price of building a tier deck to $106.42 (although your second, third, and fourth tier decks will be slightly cheaper because you'll already have the Adventure cards)
Green ramp decks now have Karn, Ugin, Sky Sovereign, Garruks and Nissas as well as card quality non-creatures at the low end
With that, the player draws an extra card at their end step
Great with the exiling, no answers or recursion
