Hadoken, as a functional reskin of Lightning Bolt, is legal in the formats where that card is legal: Modern, Legacy, Vintage, Commander, Oathbreaker, and Pauper

Of course, Im certainly no pro, and I generally dont play the Modern format that this set is largely designed around, so I cant speak to the exact power level of the individual cards here without inevitably making a fool of myself
Extraction can completely ruin Izzet Phoenixs day by stripping them of their key card for a mere two-life investment
