I don't know if I have ever done this but in a box draw I managed to clear the pitch with Undead against Rats. Turn 3 of the 2nd half:

I can tell my opponent was upset when I chose to foul a player rather than score on Turn 8 of the first half - but I had 6 rats in the KO box and thought maybe I could add a 7th. Didn't happen that way as 3 came back but it still kept me in advantageous position in the numbers game. But still, you know how Gutter Runners are - he still scored in 3 turns. With the help of Nuffle I managed to score twice in the second half though...so, yay for me. This is one of the first rat coaches I have seen that was happy to base his rats on players - definitely a high risk/reward type deal!
CHEERS TO PITCH CLEARING!
