pokemon card onix Crystal Onix! This is a custom and not a real one. Back in the day I made quite a few of these crystal cards. I'm actually surprised they didn't have hour instructor Pokemon - Onix 095/165 -

Anyway, thats the mechanic, so lets look at some cards that utilize this new kind of token

Dismember being blacks offering kind of defeated the point, but when Fatal Push was printed, black finally had a one-cost removal spell worthy of the tippity-top tier one status of those other iconic spells

Other related cards that I dont think are worthy of their own section include Arclight Phoenix which saw a lot of success before blue red spells became way too underpowered

While that extra blue mana prohibits all decks from playing the Vault, some Trix decks found room for this powerful searcher back in the day

And that's it
