What are earthbound immortals?

Answer 1

They are basically the dark signer's special monster like they signer's stardust dragon, red dragon archfiend, and black rose dragon. They all are similar in a way; they require 2 sacrifices and their similar effect is that if there is no field card destroy this card, they can attack your opponent directly and they can't be targeted in battle. I hope this has help =)

The individual effects are:

Uru - Tribute 1 monster to gain control of one monster on your opp's side of the field until the end phase once per turn.

Aslla Piscu - When this card is removed from the field, except by it's own effect destroy your opponents monsters and deal 800 damager each.

Chacu Challhua - While this card is in defence mode your opponent cannot conduct their battle phase. Once per turn, you can deal damage to your opponent equal to this card's defence, but cannot attack the turn this effect is activated.

Ccapac Apu - When this card destroys a monster in battle, inflict damage to your opponent equal to the destroyed monster's attack points.

Ccarayhua - When this card is removed from the field, except by it's own effect, destroy all cards on the field.

Wiraqocha Rasca - When this card is Normal Summoned you can return up to 3 cards on your side of the field back to your deck. Then your opponent randomly discards cards from their hand equal to the amount of cards returned to your deck and this card gains 1000 attack for each card discarded.

Cusillu - If this card is about to be destroyed in battle, you can tribute 1 other monster on your side of the field to prevent this card's destruction, then halve your opponent's life points.
