"Five-Headed Link Dragon" Rating Score by とき

A Link 5 monster that requires an unprecedented Link Summon of 5 monsters.
Special Summon can only be done by link summoning, and if you link summon using all darkness, earth, water, fire, and wind as materials, the effect of clearing the opponent's field, complete effect resistance and combat destruction resistance against light and other than God, It has a maintenance cost that removes 5 GY cards from the back side for each opponent's end.
It is no exaggeration to say that its performance as a monster is that of an invincible dragon. With this RBI, full effect resistance is violence. Moreover, it also has battle destruction resistance other than light and gods. Although it is traded against Lightning. As long as the 5 monsters don't use destructive effects, I don't care what kind of card it is, so depending on how well the Deck develops, it can easily come out.
However, there are shackles corresponding to that, and the weight of the maintenance cost is particularly serious. If it can act for 2 to 4 turns, it's a good deal, and if it can't use destruction effects, it's 5000 RBI, which is just a strong resistance, so there's a risk that it won't be able to decide the game.
Conversely, the attributes are too strict to use the destructive effect. I'm also worried about the Borrel sword with his violent ATK with 4 Effect Monsters.
