One step at a time.
2500 attack: Defeats the typical
one tribute monsters you're going to see in combat
1500 defense: Won't be wiped out
by a searcher in defense mode, so Book of Moon isn't
instant death for it.
Two Tributes: If the effect could
be enabled without tributing for it, this wouldn't
be too bad. As its a mandatory tribute summon,
however, this is enough to sink the card in all but
the most dedicated builds.
Effect: A variation on Skill
Drain, this card prevents even Exiled Force from
doing his Konami-given duty of "sacrificing for the
greater good". Does nothing to continuous effects,
Light/Fairy: Adds nothing
particularly outstanding to either stat.
Now then, here we have a monster
with a powerful continuous effect. It locks out
Monarchs, Exiled Force, searchers, and an assortment
of other typically obnoxious effect monsters. Other
continuous effect monsters (such as Jinzo and Spell
Canceller) ignore it entirely, making for
potentially interesting decks designed around
Could be fun.
Regardless, the mandatory tribute
summon hurts it deeply. As it is, we only see the
use of two other two tribute monsters right now;
Dark Magician of Chaos (who is typically special
summoned anyway) and Light and Darkness Dragon. Both
cards can change a game merely by touching the
field. DMoC is a floater, so anything he kills once
he's on the field is a bonus. LADD can take several
spells and traps with it before it leaves the field,
generating back easily the amount of resources it
Angel 07, however, does neither of
these things. While it can protect itself from
destruction through monster effects (Exiled Force,
Ryko), its two greatest threats come from Dark Armed
Dragon and Judgment Dragon... both of whom can
merely run it over.
Still, this is a format where much
of our destruction comes from monsters. With that
taken into consideration, Angel 07 does have
potential to wreck some havoc against DAD decks (if
you can hold off with Dragon himself) as well as
Lightsworn decks (again, if you can fight the
Dragon). More importantly, though, it annihilates
Gladiator Beast decks. That alone gives it some
potential use in today's meta. All things
considered, she either needs a deck built around
her, or she's a wild card side deck option.
Traditional: 2/5 (a few more cards
to negate, but a much faster format with more ways
of dealing with it)
Advanced: 3/5 (takes some effort to field, but can
deal a lot of damage to the current meta)
