I'm going approach things a little differently for this criteria than I did with the last one: I'll pick out all of the cards I really liked, leave some comments about them, and then reveal which of them I picked to nominate. And then the ones that weren't picked for nomination qualify as the "honorable mentions."
As I picked 4 honorable mentions last time, I think it's only appropriate that the cards I comment on be collectively known as my Top 5 Picks. They will be in no particular order.
Aaarrrgh--This is a nice, simple execution of what I was looking for in the criteria. I never played during the first Mirrodin block, but I've found several cards from that era which I really like. This card could have been a little more exciting, though. As it is, it only gives a choice of a 1/1, 2/2, 3/3, or 5/5. Not particularly enthralling, but it still managed to get into my Top 5.
ConfusedAsUsual--I really liked Overload (although I wish it wasn't available to only Izzet cards; here's hoping Dragon's Maze sees some cross-guild keywording). Your alternate cost is basically the same thing, except on a permanent card instead of an instant or sorcery. I don't feel it has as much flexibility as Overload does, though. And as your card was worded, I feel it's just a tad bit overpowered. I don't think they'd ever print a functional reprint of
Glorious Anthem 
with the same cost and Flash, so adding
and changing one of the colored mana symbols to green does not really warrant a +2/+2 for 4 and at instant speed. Even with the drawback of requiring a creature on the battlefield. They don't even have a flat, one-sided +2/+2 enchantment in white or green. For 4 your
Legendary creatures 
get the boost, and for 3 your
artifact creatures 
get the boost. For all creatures you control, and without flash, I feel the effect would be 5 for an enchantment, depending on color intensity. Add the drawback of needing a creature and the plus of flash, it can stay at 5.
Collective Blessing 
would probably cost 7 if it only needed
to cast (as opposed to the
it currently is costed at).
Kuro_Ageha--This is certainly an interesting card. The alternate cost is technically lower than the casting cost, but you can potentially pay more than the casting cost, so...I'll consider it as fitting the criteria. The only thing I don't like about it is the amount of damage you can deal with the alternate cost. Even if for retaliatory purposes, I don't feel red should be able to deal 20 damage for
at instant speed. Or 8 damage for
. But at the same time, this wouldn't be as impressive if it only dealt 1 damage (matching its
namesake 
, no less) per mana spent to cast it. The only redeeming quality from its wording is that a copy of this spell does absolutely nothing. Also: players don't deal damage, sources they control do.
vlord--I like this concept of casting an artifact creature as just an artifact, but I don't agree with your execution of the idea. Mostly because, as worded, I believe it would lose the
ingot 
ability. But also because I don't agree with the flavor that a statue-ized artifact creature becomes indestructible.
altimis--I only like this because it's a
Coat of Arms 
in spell form.
And then some, since it also buffs everything by the initial +1/+1 if you pay the alternate cost, although I have a feeling this was not intended. Why does it target in the first place? To give a larger range of counterability?
And so...
Show
The winner of my nomination is Geistflame Trap. Despite feeling that this card is broken, it makes me want to play it. I wouldn't think of this card as a Timmy card, but I think that's the part of me that really enjoys this retaliation card.
As I feel this may have been more or less a successful attempt at a contest for me, I think I'll continue this. So, as close to midnight as I can do it, I will post a new thread for the week of 3-26 to 4-1.
