Advanced MTG rule question?

Yes, blinding soul eater's ability can be used after blockers are declared.

I believe you got the idea wrong in your example. Tapping guard gomazoa does not remove it from blocking Serra Angel. After the creature was declared a blocker or attacker, tapping a creature does not affect their combat positions.

In another scenario, if you decide to use blinding soul eater's ability before defending player can assign blockers, then guard gomazoa cannot block. Remember, the trick is to announce that you are doing the ability before blockers or attackers are declared. This is important for tapping abilities.

The way to stop the Gomazoa from blocking is to tap it before the declare blockers step. You can do this during the Upkeep step, the Main Phase, the Beginning of Combat step, and the Declare Attackers phase.

To my understanding, the attack phase doesn't follow the normal rules of the stack. Declaring a block or attack can't be responded to, such as a tap effect or a destroy effect to prevent battle cry, etc. This is why there are separate phases: enter combat, then declare attackers, declare blockers, damage assigned. The opponent gains equal priority when you enter combat, but once attackers or blockers are declared, interrupts are nulled.

Tapping a creature after blockers have been declared does nothing to the blocking creature. You need to tap the creature before the attack phase.

you're impressive on the two debts. while the guideline references the cardboard call, it in basic terms looks on the cardboard's call. The aspects of a card are interior the 1st 2 references. The Legend Rule does not say something relating to the cardboard's type, it is got here upon interior the type line. you additionally can think of of it this way: Non-mythical taking part in cards frequently reference customary gadgets or persons. A mythical card represents a particular merchandise or individual, there is in basic terms one in each and every of that merchandise or individual. So, once you have 2 of one mythical everlasting on the sector, the gamers are attempting to summon 2 of an merchandise or individual, yet that merchandise or individual in basic terms exists as quickly as, so the two copies bypass bye-bye. you will have as many mythical angels on the Battlefield at as quickly as. case in point, Akrasan Squire is non-mythical, it may exist as many situations as you opt on it to as there are a number of Squires from Akrasa. Akroma, Angel of Wrath is mythical, although, so she would be in a position to in basic terms exist as quickly as. in case you attempt to play a 2d one, you're attempting to summon her lower back, yet she is one-of-a-kind and does not exist two times, so the two copies bypass to the graveyard. besides the undeniable fact that, you're able to have the two Akroma and Iona, shelter of Emeria in play on the comparable time. they're the two angels and are the two mythical, yet they're 2 diverse human beings, so there is no situation getting them the two out. If i'm going to quote Ben Bleiweiss, an author on the Wizards (aka the corporation that makes Magic) website, he says, "And remember childrens, the lands themselves are colorless, whether they produce all 5 colorations of mana." in one in each and every of his articles which could be got here upon interior the references. i think of that it is sufficient, yet while this is not, a card's shade is set through its mana value and not the rest using fact the third poster interior the final reference has reported. i'm hoping this enables you.
