Im rating Cyberman Patrol highly because it does a lot for its mana value, and it looks like a strong inclusion in artifact aggressive/tokens decks
Now we've pointed to that cause, there's not too much clever analysis left to do, except to sigh wistfully and imagine how sweet it would be to have heavily bought up Obeka cards when the MTG Outlaws of Thunder Junction commander was first revealed
Hoopa ex's first attack, "Energy Crush", deals 50 damage for each energy attached to all the opponent's Pokmon , which is great against decks like Hydrapple ex and Toedscruel that need to have a plethora of energy attached to the board to deal damage
I prefer Open the Armory overall because of its versatility, but specialized decks probably prefer Steelshaper's Gift
Crucible of Worlds overshot the mark a bit, though, and became more of an enabler of land destruction by looping Strip Mine and Wasteland than a way to recover from Stone Rain effects
