A pretty shitty card, a worse SRH that is slower and doesn't always destroy the card you want. TBH destruction effects are easily preventable in the current meta. It is banishing which is the powerhouse.
To 2) While you got a second monster on the field, it may not the one you can need. Especially you still needed 2 cards for just 2 monsters on the field contrary to 1 card(and 2k lp) for 3. And you would have every monster you need(anti monster, anti backrow and attacker). I don't have this deck, but those are my thoughts how it would be with those replacements for ties.
Yeah and the skill is f*cking useless and impossible to pull off. Maybe it’s possible against a standard duelist in Duel World, but a pulling off the combo of:
1. All 5 pieces in the GY
2. Exodia Necross in the hand
3. And the spell card to summon him
without dying first is impossible. The combo moves way too slowly, especially for the Miasma levels or for PvP. It needs a new skill/cards
Life cost 0 Cyber Stein should do the job
go in with HP 1000 and below with some mallet, econ, windstorm/anubis/hallowed life.
Deep diver for search.
I use gatling dragon/Jumbo drill/other suitable fusion monster.
It's impossible to summon it from outside the game in real life.
What actually held this card back, are two things:
1. This card is incredibly weak when considering its materials.
2. Mirage Knight itself is a Nomi that lasts on the field for only a turn, not worth it to use despite its complex summoning condition.
As long as you use at least one prismatic card and use Union Attack twice, you can replace the fusion summon with one Caligo Claw Crow to get exactly 10000 ATK and still get 8000 score. You can special summon Caligo because Gate Guardian is a DARK attribute monster. Means your hand is less full during the duel since you have less cards to save till the last turn.
