In this case, swapping them for a Thrashing Brontodon would be better, even if there are no artifacts or enchantments, because it's a possible attacker
And with the appearance of Greninja Radiant (from Astral Radiance), which attack that does 90 damage to two opponent's Pokmon, there are endless possibilities
Perhaps surprisingly, the biggest chase card from Prismatic Evolutions, Umbreon ex, is actually dipping in value
Although it works as a two-player game, I recommend as many players as you can get because the fun is in watching players get eliminated one by one
It wont make it into the highest power decks, but its a bit of a stalwart for the masses
Also, note it's power in any deck, but in tempo, aggro with Anthem effects, artifact and dorks matter like Losheen, Hate Bears, Auras, Equipment, Voltron, +1/+1 counters matter and more this is a must kill on sight guy
