Migosp is a cheap card with the ability to give +1 HP to the monsters adjacent to it when placed. As such, you should place your previous monsters accordingly to make full use of its effect.
Migosp and its upgraded/Hard Mode version Migospel work slightly similar, but this card is more suited for early game due to its low impacting effect, making it best suited alongside Taunt monsters like Dummy and Mace.
Unlike Migospel, you can actually play Migosp while the enemy has at least 1 monster and you don't and not let the enemy benefit from it, as the effect is limited to ally monsters, unlike ANY monster Migospel can target.
