strat question (in New players)

so my next ncb is coming up next month.

i am planning on having a single archer. right now i am gathering the gear up, which is coming to plan.

my question is should i train another minion with him?
if so an enchanter i would guess but what would be the best thing for him to train?

any tips would be greatly appreciated.

Any form of offensive magic as you'll encounter evasion that your archer won't be able to overcome easily. Then balance that with an anti magic field.

i was thinking antimagic field and ablative shield or protection
