Fun Interaction: Ghalta the Immovable & Tetsuko Umezawa, Fugitive
I built a Standard deck on Arena around the following cards (in ideal draw and turn order).
Turn 1:
Aegis Turtle
Turn 2:
Dive Down (or Chase Inspiration)
Ghalta the Immovable
Turn 3:
Tetsuko Umezawa, Fugitive
Aegis turtle with Dive Down makes Ghalta cost 'W', allowing a turn 2 drop and an 8/8 turtle attacking. Tetsuko makes your turtle and Ghalta unblockable.
Hadn't seen this combo listed before (though I'm not heavy in the community). What would you add?
