Tournaments hassles HMM II

Good day!
Here are some options: a tournament for the fastest completion time, an arena, a competition for hero experience, for the number of skeletons, or for reaching a specific hero level the fastest.
Due to the high number of potential participants, I suggest we play a SMALL tournament for speed. The map should be small or medium-sized (preferably small) and not too difficult.
For the tournament, we need:
1. To finalize the system;
2. To gather at least 5 participants who are GUARANTEED to complete the tournament, without dropping out.
I await suggestions and new participants.
