lets start to think of "team opps"  which can be casted for a attacker/banker pair.

for example me and dimpel are a team, im banking hes attacking.

* i can cast a spell that for the following 10 ticks 10% of my income will be paid directly to him.  (good for overnight upkeep)
* he can cast an opp that would entitle me to his attack bonus for 5 ticks,  so his reduces and mine increases.
* he can cast an opp that would instantly put a planet of his under my control (no more travelling 500 ticks to a planet) 
* i can cast an opp so i can take planets from him even when defence is present. (no more having to remove lasers on 100 planets)
