The History of Poison in MTG Poison counters debuted in 1994s Legends on Pit Scorpion
This card is old, though, and Im sure an equally flexible card must exist by todays standard in a tri-colored Charm thats black-bordered
Extra turns can win you the game, or at the very least help you catch up if youre falling behind
Note: There was no Machamp (8/102) included on the disco holo test sheets, as such this set of 15 is the full extent of Pokmon included in the test run
Cards like this aren't printed in black border for a reason, and this card is a good example of that reason in action (see City in a Bottle and/or Apocalypse Chime for more examples like this
Meanwhile, Yennett, Cryptic Sovereign is one of the most interesting build-around commanders in the set, facilitating a brand-new archetype in odd-converted-mana-cost tribal (while still being fine on its own, with the double evasion making it pretty easy to draw an extra card each turn if you can't cast that card for free), while Varina, Lich Queen finally unites all of the colors of Zombies, so if you are looking to add the white Amonkhet Zombies to the blue Innistrad Zombies on the traditional black Zombie base, she's the best (and only on-tribe) option for your commander
