Black Luster Soldier? Not extremely broken; however it's very, very powerful. Its presence caused Chaos decks to dominate the metagame for a year or two, and it was finally banned. It was because of this that Chaos Sorcerer was banned as well for a time (Chaos decks dominating the game, rather).
1 Tuner Synchro Monster + 2 or more non-Tuner Synchro Monsters
This card cannot be Special Summoned except by Synchro Summon. Once per turn, you can negate the Summon of a monster, and destroy it. When this card is sent from the field to the Graveyard, you can select 1 "Tech Genus" monster in your Graveyard, and Special Summon it.
Ok, it can be Bottemless'ed and all that, but Christ. A 4000 that can negate a summon? That is pretty God damn good. And it doesn't even matter that you need 3 monsters. With the likes of Glow-up bulb easily being brought out with only 1*.
Correction. You need 3 SYNCHRO monsters. That is SIX monsters (at least!). Very difficult to Synchro for if your deck isn't built for it therefore.
It is not easy. Something like Hyper Librarian + 5-star + Formula Synchron or Hyper Librarian + Wonder Magician + Recipro Dragonfly is viable, but with Hyper Librarian's superbroke-ness likely to be gone very soon (next banlist)...
To sum it up, this card is good, but only in a dedicated deck. It isn't easy to get out at all unless you build around it and Hyper Librarian.
No, Mirror Force destroys all attacking monsters. Useful, a bit, but nothing compared to this:
Doesn't have a wide area, true, can be countered, also true, but this removes from play, aka your opponent's monster is probably not coming back.

Yes, you already have.
How much of a life saver is this card?
Activate only when you take Battle Damage while you control no monsters. Gain Life Points equal to the Battle Damage you took, and Special Summon 1 "Malus Token" (Fiend-Type/DARK/Level 1/ATK ?/DEF ?). Its ATK and DEF are each equal to the amount of Life Points you gained by this effect.
Apple of Frigg is lame because it's a Trap card. If it were a monster then it would be amazing (Gorz-like...) but it's not. : \ The token is highly irrelevant (Brionac blows it up) and it's Cold Wave / Trunade - able.
Actually... Atomic Scrap Dragon is the one Scrap Synchro monster I will never, ever run. Helping your opponent recycle cards for free is usually horrible, and thus its effect is only situationally good. Furthermore, it's not easy to Synchro for (not something like Golem + Beast or Golem + Goblin or whatever; no, you don't want to ever run Scrap Soldier). It's not a very good fit in Scrap decks, which have fairly tight Extra Deck spaces as it is (what with triple Scrap Dragon and typically double Scrap Twin being mandatory).
