* Since each "Sons of Horus" requires itself to be in the [[Graveyard]] to Special Summon themselves, anti-GY floodgates such as "[[Dimension Shifter]]" or "[[Necrovalley]]" can effectively shut down the deck from making any plays.** It should be noted that "[[Necrovalley]]" does NOT prevent the Summoning of the "Son of Horus" monsters, as their Special Summon effect were an inherent [[Summoning condition]] and not an effect that move themselves out of the GY.
