I attempt to load up locations with high power one cost cards such as Ebony Maw and Titania. Yondu also helps Knull and Death when destroying a card so I tend to play him turn one if possible. The strategy is very simple for the combo, turn 3-4 Wave into Galactus or turn 4 Psylock into Galactus. Galactus will blow up the whole board giving you a very powerful turn 6 swing with most of the time a free Death and a very large Knull to close out the lane. I know Shang Chi could end your high so be smart in holding Death until turn 6 or even giving them priority going into turn 6. I use Killmonger not only to feed Knull if Galactus is not being drawn but to clear a more favorable lane I already played 1 cost cards into for Galactus. Cards you destroy with Shang Chi also count towards Knulls overall power so keep that in mind if Knull becomes your primary win condition when not drawing Galactus. Be smart when playing into lanes, you do not want to telegraph to your opponent that you will be focusing on a lane for Galactus. This is my favorite deck I have used so far and is very consistent especially with the inclusion of Chavez. Could switch out some card for a more destroy package to give Knull more consistency in the chance Galactus is not drawn. I hope you enjoy my list as much as I do!
