おそ松さん Hesokuri Wars: Netherworld Majiyaba Strategy Stage
The Netherworld Majiyaba Strategy stage is a limited-time only strategy stage where the game forces you to choose the required units to complete the stages. You can find out by going to your team summary section and tap on the Netherworld icon to sort out which units you can only play in those stages. In this case, the only 4* units I can play are Akuma Rider Karamatsu, Akuma Rider Todomatsu and Youkai!Jyushimatsu. However, I'm able to choose anyone from the FrankeNEET set. In this case, I chose Osomatsu and Choromatsu. Basically every Matsu is on my team except Ichimatsu.
The strategy is simple: I just sent out whatever I have, putting my main focus on Jyushimatsu and the Akuma Riders. The other two are only there to act as cannon fodders. Apparently Karamatsu and Todomatsu made a very good team and they were able to attack Dekapan no problem. With Jyushimatsu attacking in the air, he was able to fly pass all the ground units and became the first one to attack the enemy base. I have to say, this is the only strategy stage I am most satisfied with.
