No problem, hope your come out on top.
Just cause I'm nice (and kinda bored) here's some in-game advice too:
1. Pack 2 Forcefields. If your Forcefield gets Seeking Dispel-ed, it's imperative that you have a back-up.
2. When considering spells to bind to your Thoughtspores, use cheap ones that you can cast early and often over more expensive ones. I personally have had a lot of success with Invisible Fist; it's pretty cost-efficient and lets you punish creatures that get too close and provides some much needed dice early game. Use Arc Lightning instead if you opponent summons an Iron Golem (those really suck to deal with as FM if you aren't prepared, and are a serious pain even if you are). A good tactic in general is to keep your Thoughtspore 2 zones away from your mage, so it's close enough to quick-cast the Fist/AL if you need it, but far enough away not to go down too easily.
3. After your first Thoughtspore dies (it's gonna happen once your opponent realizes how important they are), I highly recommend summoning another one, probably with Minor Heal if you've taken a good bit of damage. If your opponent isn't far enough ahead to finish the job, multiple minor heals, while pretty annoying and cheesy, can really get you back in the game if your opponent doesn't nuke the Spore down quickly.
4. The Invisible Stalker is a great card, but it's not as untouchable as the name might suggest if you don't play it right. Try to make sure it's the very last creature you attack with every round; that way, apart from expensive zone attack spells that ignore invisibility, your opponent will have a very difficult time dealing with it.
5. Consider the defensive uses of Force Pull. The Forcemaster doesn't have the kind of creature support other mages do, and you'll find that it can be hard to attack without your mage taking a lot of damage or one of your Spores getting nailed and quite possibly dying to a heavy attack spell like Fireball or Hurl Boulder. A good tactic I like to use is to activate a Spore, move, cast Fist, and then Quickcast Force Pull to get it out of range at the end of its action phase. It's kind of like boxing, but with your brain
.
You can do something similar with Psyloks, but instead keep the Psylok a zone behind your mage and then Force Pull it in at the beginning of its action phase, and then attack with it. Also, don't be afraid to guard with a Psylok if you need to; better your brain pet than you. Yes, Psyloks aren't terribly impressive, but the Forcemaster is starved for extra actions more than any other mage, and Psyloks help keep her action count up.
6. Finally, put a wall with a Passage Attack trait in your book. Summoning a wall and then pushing a mage through with Force Push can be a nasty surprise, and a good way of separating the opposing mage from any guard he or she might have. It can be a nail in the coffin when you really need it, or a good way of breaking Line of Sight if you're afraid of getting killed with a nuke (Wall of Fire covers both purposes, but is more expensive than Wall of Pikes, so it's really a matter of preference).
Ok, that's all the in-game advice in my brain for now. The Forcemaster is my second-favorite mage after the Warlock, but that's more because I like her odd creatures and witty playstyle, which is a break from the Warlock's all-out, straight-forward aggression. Stay open to the brain-mage, and you might find that you like her more than you anticipated
