Delta archer (Genie skills)

I've done dozens of deltas and i was just wondering if there was any genie skill that would help me improve on this particular game event (not really an event, but whatever...). I dont use charms, and there isnt really any need. 1st stage you get by with event mana pots and at stage 9 you can maneuver quite well with event hp pots and maybe apot/wingspan if something gets out of hand. Of course, rebirth isnt just about you, which brings me to my question: What are the best genie skills an archer can bring to delta to better assis squad?

Atm i use:
1 - Tangling mire - Dont use too often as most of the times it isnt needed, but sometimes you need that extra dmg to clear a wave faster before it ends up stacking. I like this mainly on stun waves. Random people always say "Worry about defensive genie skills and anti-stun". I myself rather go for the quicker kill, and pretty much every sq i go with appreciates. So obviously ill stick to what works.
2 - Expel - To be honest, i never used this. I got it only cuz most of the wizes i went with complained i never had this skill and it helps them not get *****. Whenever i remember to use this, the hard part is already over and theres no need to use it anymore. Its like, the wave comes on them, they use expel, we DD most weak/normal mobs, and then when it would be my turn to expel wiz, the situation is already handled and its not necessary anymore. Ill keep it just to make wizes feel safe and if for some reason something goes wrong.

So thats 2 skills. My current genie can hold 5 (its a zeal, so thats 1 less slot). What 2 other skills would be useful in delta? Are ToP or 2nd wind even handy in there?

Any sugestions on skills or even stat distributions are appreciated
