Koffing (Mythical Island) is not available in Rare Packs
Pokemon Card Strategy: So as far as strategy goes, let me say right away I wouldn't use this card in my deck, however if I did, I would keep it on my bench and wait for my opponent to put into the active Pokemon spot a stage 2 Pokemon, I would then put Omastar into play and use Time Spiral, then retreat Omastar the next turn
However, things change quickly on the secondary card market
That is it for this set of Kaldheim
What if a creature card in a graveyard has no name
That's just one example, but that can apply to Charizard, Lost Zone Tina, Palkia, Bax/Pao decks that tech Palkia, and if you fail to knock off a Bravery Charm Miraidon can take advantage of that safe line of play too
