Wizard is a grind deck : the more the game lasts,the highest are your chances of winning.
What is so cool with Wizard is that there is no right way to build the deck. There is an infinity of possibilities to build it.
Just keep in mind that you need to keep a balance between
- Card advantage producer (will glassart, Nice one)
- Gauge economy (Andy, Key of solomon (Kos) first volume)
- Defense (Chillax, Kos 2)
- Threats to pressure your opponent (Quinus Axia, Merlin, Grandfather's clock)
- Fixers that fixes the lack of board control
