No one on the playground knew how to properly play the PTCG, and I wouldnt learn until 23 years later
I only include cards that are mono-green, although there are interesting multicolor counterspells that dip into green
However, turning a face-down creature face-up doesnt cause it to leave or enter the battlefield, so it wont trigger creaturefall
Sure, it works with Spacrafts, but unless White is one of your strong colors, dont go out of your way to play this
For example, Deathrite Shaman was only banned last week on Magic Online
You want the minimum number of counterspells in your deck to ensure you are safe against all the possible things that are dangerous to you
