ruby and sapphire pokemon cards EX Blister Pack ex has been Knocked Out Magmar EX - EX Ruby

To play this augment card you have to pay to play it over a host creature thats already on the battlefield, which would be Mer Man in this case

Your cards function should determine the type of stock you choose

It's a strictly worse version of Gaea's CradleGaea's Cradle (although this one taps for mana even without creatures, so maybe...), but this can be said for the vast majority of lands in the game

Real cards allow some light to pass through, while the counterfeit is either too thick or made with different card stock to see any glimpse of light

For my build, I went for big beaters

These cards use the frames and treatments found in their foil printings but without the foil treatment (such as Nexus of Fate above)
