ToA vs Junctioning a Hal? (in General)

My current strategy is two minions, one with a huge EC, base decay, and then a ToA sling of death minion. With my NUB being gone for a month now, I realize it is impossible to keep upping my weapons with the best of CB. All that free NW of the Hal is very tempting and if I were to get a few pointers on the switch, it would be great.

Going huge DM with a Hal and a regular tank/archer is very solid. Junction the hal to your enchanter and get yourself a TSA and EC to make up for the ToA (definitely is a good trade). Unless you are considering dropping your tank dude since you mentioned weapon cost. In that case, DM and AS are solid choices, maybe throw some PL around....
1. DM, junction hal
2. PL, AS

Or something like that
