If Cross Porter is tributed for Horn of Heaven, can you still add a "Neo-Spacian" monster?!
Horn of Heaven is activated and Cross Porter is tributed as the cost.
No. Cross Porter misses timing because it was sent as a cost to negate a Summon.
Can Horn of Heaven negate the Summon of Elemental HERO Absolute Zero if it is Summoned by a card effect?!
Elemental HERO Absolute Zero is Special Summoned by a resolving card effect.
No. Horn of Heaven can only negate Summons that occur without a chain, not Summons that happen during the resolution of an effect.
