If you anticipate playing against any sort of Planeswalker deck, I would highly recommend including a copy of this card in your deck(s) with black in them

And you can also just Irencrag Feat into Purphoros for quick kills, and oh look theres a Throne of Eldraine card causing problems yet again
Then, on top of that, add light support, in the sense that it takes few card slots, that works for any tribes
For example, if a player who controls Alhammarrets Archive would gain 3 life while Tainted Remedy is on the battlefield, that player may choose to have the 3 life become doubled to 6 life and then lose 6 life
There was no tap symbol when the game began
