Next we have a pretty clever deck to punish double black lotus decks: If the opponent goes, say, Black Lotus, Black Lotus, Grave Titan, then Mindbreak Trap will counter the Grave Titan
It's an aptly-named card, since it's mostly commonly seen producing infinite combos with Sensei's Divining Top and a cost reducer
Like every other TCG, Magic: The Gathering is by definition a social game, even if you just play a quick game or two and barely interact with your opponent
I might even suggest taking out Mind Flayer, the Shadow or Emrakul, the Promised End for it, as in my opinion the dragon is a more efficient option for the same mana cost as Mind Flayer, and is more synergistic than Emrakul
If you have played a lone Nazgl, your wraiths get one +1/+1 counter
