yugioh centurion cards - Stand-Up Centurion! Centur-Ion Atrii | Card Details

I also have the First three sets complete (basic, fossil, jungle), some extra collector sets (pikachu world collection, and a few neo sets), and all of the BK gold cards (unopened and in box)

And Do the Wave is awesome

The next group of cards that can sell for a lot is the rare holographic Pokmon cards from classic expansions

So if you control a level 4 monster, you cannot special summon another level 4

You can only use this effect of "Invoked Oceanus" once per turn

So you cannot use one creature to pay for multiple sacrifice costs at the same time, nor can you play an instant that your opponent has already forced you to discard to still gain its effect
