GBx midrange decks are most commonly associated with targeted discard spells like [c]Thoughtseize[/c], efficient removal spells like [c]Fatal Push[/c], powerful creatures like [c]Tarmogoyf[/c], and grindy planeswalkers like [c]Liliana of the Veil[/c]
Unlike flavor-of-the-month lists that reach a peak in popularity and then fade away because of counter decks (such as the one-time top-ranked Charizard Ex and Sylveon Ex list that faltered with Oricorio's return to popularity), Darktina has adjusted to each format adjustment, GameRant wrote
Players can cast spells after Elder Gargaroth's triggered ability has resolved but before blockers are declared (if it's attacking) or before combat damage is dealt (if it's blocking)
Best starting point: A smaller modern set like Paldean Fates or Pokemon 151
Commanders like Lord Windgrace and Titania, Protector of Argoth can do a lot with this
However, if you activate an ability whose cost has you put loyalty counters on a planeswalker, the number you put on isn't doubled
