@PB&J: I think you made a typo. I am assuming your Alm is -SPD/+RES. It depends on what you want him for.
-SPD with Windsweep is still very useful since Summoner support+Phantom SPD3 gives him a total of 39 SPD before including any buffs or A skill.
Renewal 2 so that you heal 3/6 turns consecutively (double heal on turn 1, no heal on 2, single heal on turns 3, 4 and 5, no heal on turn 6, then repeat). This mean that he can kill 2 people on turns 2 and 3 then still have his Double Lion ability on turn 4 without the need of a healer. Renewal 3 will heal more BUT with no consecutive turns giving him more "off" turns.
If you are not planning for drawn out battles where you will need him to fight multiple enemies, any breaker will do to guarantee the death of 1 unit.
Drag Back/Hit and Run are great for allowing him to safely retreat after attacking.
Lunge is fabulous for catching people off guard and netting Arena Def wins. (Knockback is useless unless you have a way to survive the initiation and have allies that can warp to the empty square)
Shield Pulse will give him instant Turn 1 Miracle allowing for guaranteed wing of mercy shenanigans.
QR allows him to have more EP presence.
Cancel Affinity helps him deal with TA blues.
2 CD + Heavy Blade seal: your alm doesn't have upper echelon's ATK so he won't make much use of it, especially against inferno or advanced arena maps. Besides, your Double Lion won't always be active after the first use so 2 CD + QP seal is better.
Sadly also because you won't always have the Double Lion effect, odd numbered skills aren't versatile either. Gale Force+Breaker is a good combo. Once you activate Gale Force, you can immediately retreat and use Reciprical Aid on an ally to fully heal and have Double Lion active again for the next action turn.
