No archers nor horses - Infernal

Ike +spd/-def @ Ragnell/Swap/Aether/Heavy Blade 3/Quick Riposte 2/Hone Speed 3/Attack seal
Ephraim +spd/-hp @ Siegmund/Reposition/Bonfire/Triangle Adept 3/Lancebreaker 3/Hone Speed 3/Fortify Resistance seal
Nino +atk/-res @ Gronnblade+/Draw Back/Growing Wind/Life and Death 3/Desperation 3/Hone Attack 3/Speed seal
Olivia @ Dance/Hone Attack 3

Start Ike off in between Olivia(right) and Ephraim(left) with Nino south. Have Ike march inside attack range of the archer and axe flier with dance, so he doesn't get hit by Panic Ploy. Place Nino next to Olivia and put Ephraim where Nino started so he can reach the red mage next turn.
