Qualifications

Preserve life. Every decision downstream of that gets easier.

Wrath at X=2 clears most of their creatures and Goblin Bombardment, Rest in Peace, High Noon and Vexing Bauble alongside them.

Riddler is the post-sweeper threat, and it does not care what they boarded against your graveyard.

Fetch basics before the Blood Moon turn, not after.

Preserve · · · · Atraxa over Griselbrand in every game. Your life total will not pay for seven cards here.

Avoid · Overcommitting Frog and Archaeologist into your own Wrath.

Avoid · Spending removal on every one-drop when a sweeper is a turn away.

Avoid · Reanimating because the ceiling looked higher.
