Two turn play, two card combo (three if you count raviel)

Summon goblin king (Fiend/LV1) and set league of uniform nomenclature. Flip it on your opponents turn and he is staring at 3 fiends of 3000 ATK he cannot attack. Your next turn you play it for as much damage as you can, and then tribute all three of them for Raviel in main phase II. You can then still set another monster, even a tribute monster, because you'll get a phantasm token.

That does not work because The League of Uniform Nomenclature can be used on Level 2 or lower normal monsters.

The League of Uniform Nomenclature
Select 1 face-up Level 2 or lower Normal Monster on your side of the field to activate this card. Special Summon from your Deck to your side of the field as many cards as possible with the same name as the selected monster.

this stops that right in its tracks

No only that, even if League of Uniform pf Nomenclature could work on Goblin King, their ATK would be 2000 each, not 3000. Goblin does not include itself in the ATK calculation.

Crap, I hate those little phrases like "normal".

And yeah, I saw my error in calculation after I had already posted. Regardless, that wouldn't have hurt the combo. Just the fact that league doesn't work with goblin king or giant germ. That immediately makes it a 3 (4 with raviel) card combo and not that feasible.

I found more success using things like Giant Germ and Dark World for summoning it...or Dark Necrofear + RftDD, but that's more situational.

Yes, if it had been a valid combo I was thinking of the opposite. Summon raviel and keep necrofear as the back-up to feed on your tributes for raviel and his powerups. Then close with RftDD.

Combo would still work with a normal fiend and heart of clear water, but 3-4 card combo's are harder to play than just playing it by ear.

I actually found Skull Knight #2 to be ok with the Decktype...tribute one #2 for Ha Des, Summoned Skull or something, get another...repeat next turn or even that same turn with Ultimate Offering, bring out another Tribute and get another #2 and 3 monsters there.

Still a little situational, but then again, a lot of stuff is.
