I have a good card of the day strategy. I'd like you to try it out. Here it is:
Have Fred & George Weasly out in play with a gringotts/sickle/winning Gryffindor
Match last turn. You only need the Weasly twins if you only get 1 extra
action. Then you play a Diagon Alley for 1 or 2 action(s). Then you play
Draco's Trick so you get the reward for your adventure, which is draw as many
cards as you want. Draw every card in your deck except one. That totals up
to 2 or 3 actions. For your third or fourth, play spiral dive
and discard your whole hand. This should win you the game. I got the strategy
from this site and made a few variations. If you do get four actions and you
have a Fred and George Weasly in play, I recommend damaging your opponent with
5 or more damage before using this strategy.
