7s/streetball tournaments - help with lizards

[havik110]

Hi all,
New poster. I have been going to 1 tournament a month for a while now and they are mostly playing 7s or streetball so we can get 3 games in relatively quickly.

The games are generally 700k with 100k in skill ups (20k normal, 30k doubles)

I have been playing Lizards and have generally been liking 2 saurus with block/mighty blow and 1 with guard.

So my question is can you think of any ways for me to improve this? I have been thinking of frenzy on 1 to keep people out of the outside 2 zones. Ive also thought about shadowing

Thanks for any help
