The Pokemon Company Quietly Updated Its T&C This is the part most collectors missed
Pay the cost, discard Shark Typhoon, and you can create a flying shark token with attack and defence equal to that extra mana you paid.
Despite these new solutions, older cards still keep their original text or updated Oracle text that says Regenerate. If you own those cards, the rule is still valid: you can pay the regenerate cost, you can save your creature from lethal damage, and you still get to keep it on the battlefield, albeit tapped
The battle card shows a fairly unique crystalline elemental as well, which, when added to the lore we get from the viashino on Karsus Depthguard, begins to give us an idea of what Karsus is all about
It's all free, so if you're a Pokemon fan there's no reason not to check it out, especially if you're a fan of the videogames who's curious about the TCG.
MANA CRYPT My personal pick as the most powerful card legal in Commander
