Possible ways to bring teemo into OFA

1. Don't let shroom damage stack.
2. Make it so there can only be a certain amount of shrooms placed per teemo (Ex- 3 per player)
3. Don't let poison damage stack.
4. Make an immunity to blind after you've been hit by it once (so they can't prevent u from attacking forever). Ex- When blind is lifted, no more blinds can be placed for 2-4 seconds.
5. Same thing as 4, but for ult damage.
6. Don't let them all be invisible in the same area (Example: put an area around one teemo that stops others from going invis near them).
7. Haha didn't notice that there was no 6?

Most important ones, however, are probably 1,2,3, and 4. I believe this will stop teemo from being BROKEN in OFA, but still let him be in it.
