I remember back in a Magic: the Gathering WMCQ event in Manila where I piloted a Naya Planeswalkers deck with some mana-fixing, spot and mass removal spells. It was a quite grinding build but the objective for the late game is to dominate opponents with your super friends.

During the last days of Standard before the pandemic, I’ve looked on our Grixis Planeswalker deck which we had in our team roster and while it was note quite popular because of the majority of Flash decks that counters it, it was shelved only for playtest use and minor local tournaments.

For today’s M21 Standard deck feature, we have a similar deck with the Grixis colors but having White as the fourth one. This opens access to Elspeth Conquers Death, Teferi, and Baneslayer Angel in the sideboard as the powerful part of the late-game plan and that will really gain value and at most will win you games.

I found this on the Best Decks column of the Player Tour Finals held last July 25th, 2020. This was played by Bolun Zhang which he got 27 pts & here below is the decklist:
