I would like to talk about what you do at the first move of the game since it's simple.
We have 5 possibility :
1 - Risky, but can give a good thing.
2 - Useless, except at 2 or 3 players where you just use one card for gain one point and if the creature use one of his best card for block 1&5 it's really good.
3 - Give a good shot for second turn, which is good too.
4 - Few usefull. Seem like a low risk like the 2. One card let you use the effect on an adjacent tile, which is really good with it.
5 - The best one for gain another card.
As a player, I think I will go most of the time on 5 (45%), a good amount of time on 1 (30%), regulary on 3 (20%), and sometimes on 4 (5%).
As the creature, I will try to block 1&5 and put the best token on 1 for remove 2 live.
Now, with many players, there will be a good chance someone will go on 1 or 5. So, I think you should in theory reduce the amount of time you go there? And put more 3? And more 2 turn 2?
What are you though about this? It's obvious 1&5 are the best move if it work. If it work...
