Four's A Crowd Modifier always makes battles feel more intense for me. With only four units allowed, every slot becomes very important. You cannot rely on extra support units so each one needs to do multiple roles at once. Tanks must deal damage and damage units must also survive longer. Because of this, I tried to build a lineup where every unit contributes both offensively and defensively while keeping the whole strategy intact.

This team is, I think, the best of what I can do for now. I used strong units that can act both as damage and tanks since I am only allowed to use 4 units in this battle due to Four's A Crowd modifier. Even though Zyrx the Emberglace has good stats, I want to keep him safe so Ulundin Overseer takes the front instead. I gave Blast and Deathblow to the three attacking units at the back and that improved my damage by a lot since every attack now affects more than one unit. I was also lucky because the enemy tank and Taunt unit, Silverleaf Mage, was placed in the middle of their lineup. This made my attacks hit the middle as well which allows my Blast to its full potential and hit 3 units at a time. With these multiple stacking luck, I won this game very easily.
Modifier 1: Four's A Crowd. Up to four Units can be used.
Since you can only use 4 units in Four's a Crowd modifier, you would always want to use the strongest units. Usually, the higher the mana, the better stats and abilities the units have. This isn't always true but it's mostly correct.You still need to watch out for the unit's synergy and the strategy of your whole team.
Nidhoggr: I want to try out something strong in this season so I splurged a little on my rentals. Nidhoggr is far from perfect but the abilities that he give can change the battle a lot. Nidhoggr can give Blast and Deathblow to 3 units or Execute and +2 speed to 3 units. He can also reduce the enemy's health and armor by 1 which is very good overall.
Ulundin Overseer: My real purpose for Nidhoggr is the unit behind this one. I got Ulundin Overseer though because of the Flank and high defensive stats. The Flank allows the next unit to attack with melee while being in a safer position. You can think of it as the next unit having a second skin in the form of Ulundin Overseer. He is a big wall that allows your units to function fully while not reducing the damage done by your team.
Zyrx the Emberglace: Zyrx the Emberglace is the perfect unit for Nidhoggr. He has two attacks, 2 magic damage and 5 melee attack. Both of these attacks can trigger the Blast from Nidhoggr making him a terrifying unit. His defensive stats are also high enough to be a tank. 4 armor, 10 health and 4 speed for a level 1 is nuts. Still, since he is my main carry, I want him to be in the safest position possible hence, I use Ulundin Overseer or someone with Flank. There is a catch though. Zyrx the Emberglace requires a high 10 mana to use. While he has Flying ability to help him survive more, the Incendiary deals 2 burning damage to your unit's health every round. This also spreads making him a bad choice for a long game.
Sorrow Harvester: Sorro Harvester is unironicall my filler. I found no better unit so I had her instead so she can double the reduced health with Nidhoggr. With Weaken and Nidhoggr's ability, the enemy team suffers from -1 armor and -2 health which is very huge if the enemy has units that doesn't have high health.
Night Reaper: Night Reaper is a strong unit as well. It costs a lot for its stats and abilities but I found him reliable. Night Reaper has 3 magic damage which is nice with Nidhoggr's Blast ability. Night Reaper also has 1 armor, 9 health and 4 speed. He has Flying to help with survival and Wingbreak for more damage targetting other Flying units. Overall, he is a strong unit in my opinion.
Four's A Crowd Modifier is a battle where you use your strongest units and synergy. With Blast and Deathblow applied to my attackers, the damage quickly overwhelmed the enemy. The lucky positioning of their Taunt unit also helped me secure an easy win.
