Noxious Revival and Hall of Heliod's Generosity can set a Saga from your graveyard back on top of your library for a guaranteed hit
Urza's Command can drop the power of other player's dorks out of nowhere, make a Powerstone, make a tapped Construct token to win the game, and then scry and draw, so I think that the Construct and scry and card draw are the default here, and that's pretty good for four mana instant speed
Both of these card games are a great way to relax, spend time in good company, and train your math skills and logic
If they refuse to send new pictures (or never message you back), dont buy from them
With bounce lands like Simic Growth Chamber, you can start making extra mana early, especially when combined with cards like Explore or Arboreal Grazer
