1. Play last will
2. Offer 2 monsters on the feild
3. Get out 2 monsters (thats how L.W. works, even check the official site)
4. Have the 2 monsters be cannon soldier and any card
5. Offer the other monster to do 500 damage, get another card because of L.W.
6. Repeat "step 5" 10-20 times to do 5000-10000 damage

note:
this combo follows all the rules, it WORKS. Last will works like that, and you can use an effect thats not a flip efect infinate times.

note:
wabaku blocks this.
