Synergy in CMC

So, a lot of my posts have been trying to get more cards with more synergy to make CMC more interesting.

Of course, because the topic was just about boosting cards in general, other and better(pfft) ideas were suggested. Well, this thread is about boosting underpowered cards that may or may not have synergy already. By giving them synergy (or improving synergy they already have.)

Starting with Lowly Slime

This just doesn't seem as good as it did when the idea was first presented to make it destroy itself and make another slime gain half its stats.
Only idea I've got is
Destroy Lowly Slime: Target slime gets 75% of Lowly Slime's current stats.

Onto Skeletal Soldier.

This card just isn't worth it most of the time, and the 15 life second life hurts more than help most of the time, unless you have enough board control that you can afford to pay the 15 life and 5 to keep bringing it back out. But most of the time, unless you're running the one synergistic card that skeletons have, it's better to just run Garshask, Winged Demon, K-Golem, or Media Player Ray.
Ideas:
Destroyed: Gain 5 life for each other skeleton you control.
or
Has +5 attack for each other skeleton you control.

Next is Lumi

No changes to the ability, just change type to unique cleric hero.
For flavor reasons.

Now, K-Army Guy

This seems like the only 1-mana monster that's now fucking worthless in my opinion. If you ever play it, it's probably going to be for its attack, and not its ability. Holy Acolyte, Kelar Citizen, Lokar Guard, and some others I probably can't think of right now have decent synergistic abilities, so I don't know why we should leave K-Army Guy out.

My suggestion is to have all soldiers gain +1 attack for each other soldier in play. Though I'm worried this might bring back K-Army Guy rush, but at least it'll take four K-Army Guys total to just get that +3 attack bonus.

And now a card that definitely needs to be brought up again. Wrench System

Yeah, this card is still no good. Knowing the names of the cards in your opponent's hand just isn't worth an effect slot.
Hacker synergy. That's what it should have. I just dunno what to do for abilities.

and now, Shining Dragon

This card isn't really worth running, and I doubt another cost decrease or a slight stat increase will make people run it more in light decks. So why not have another card that boosts Dragon decks?
Idea(thanks to Serith):
Dragons take 25% less damage.

Next up is Norlaan

He has a nice ability if you want to spend the mana for him, a Melrak Recruiter, and snipers. Or alternatively you can use VCH Sparks for a similar effect. I sort of want to go the Melrak Chantress route with this, but it might steal prime Norlaan's thunder.
Idea:
End phase: Undizzy all other followers and they gain +5/+5.
or
Draw Phase: Heal all followers you control.
Personally I like Draw phase: Heal all followers you control the best.

And another dragon. Venomic Dragon

While the 95% ToD and the high life is really nice, this card doesn't see much play. That's because it's really not that great. Let's keep with the venemous Theme and give it,
Whenever a monster is destroyed, all non-dragon monsters are poisoned for two rounds.

Trophy card now. Magmite Soldier

This should really have the soldier type. Why doesn't it?
This is also really weak compared to Jack 'o' All Trades. I guess the more life and burning is nice, but in my Magmite deck, Jack was a lot more useful with Volcano out. I sort of feel like it should have +5 attack. Or some other Magmite synergy ability. I'm not sure, you decide.
Also, Serith says the Burn status effect needs a stat boost and I'm inclined to agree.
Though so far my only idea is 10 initial damage.
(Also, Fire Kitsune can burn magmites? What's up with that? That doesn't make any sense. It's not important, but still.)

If you have any suggestions for changes, then please post them. Just remember the point of this thread is to introduce more synergistic decks. Not give all the cards +2/+2 stat increases.
and that's all I can think of for now. I'll probably edit it tomorrow when I get more sleep.
