The Aquanix

Whenever we win a game, we're greeted to the image of a juggernaut. It's cool, badass, and to top it all off we get a victory tune that is different based on the faction we used to win with!
However, i always wondered...Why doesn't the image change as well? Why don't we see creatures like the Tremor or Dreadnought for frost victories? Grimvines or Thornbarks for nature victories? Harvesters and Overlords for shadow victories? Victory screen differences are just a small aesthetical change but one i would personally like to see.
Why not even include victory screens for the splash factions? If that's possible?

So, we all know that Beginner chat exists. All of us new players talk there to get advice on how to play the game and have others help us get started, but what about those that need help going into the bigger leagues?
I myself have had a huge anxiety issue when it comes to expert maps, not wanting to get in the way of people who actually know the map. So with this in mind, i'd like to propose a potential and small addition: A new chat type similar to Beginner, but for people who want help with expert maps or to have veterans tutor them in-game for it.
It might be unnecessary (and it probably is), but i want to put the idea out there.

I would love to see extra categorization for our cards, specifically for one aspect in particular.
Being able to categorize all of your SPARE cards, essentially if you were to have a card fully upgraded and charged, but you have another card of the same type, it is a SPARE.
By categorizing, you have all of the spares easily accessible for selling rather than having to scroll through and find them all.
 
In general though, extra categorization would be welcome in my book.

On the topic of making underwhelming cards, or those who are simply outperformed by another card that does the exact same job but better, i'd like to suggest a potential rework to a card i used to enjoy greatly in the past but realized that it's simply inferior to another card.
The Executor. This card on the surface just seems to be a Medium Wrathblades with an identical ability, not much different. Which in and of itself isn't bad, but it is simply outperformed by the Nox Trooper, who, while not dealing as much damage per hit simply has the huge advantage of a ranged attack AND a charged attack that can do massive damage. To top it all off, it is an M counter who's ability will not hinder it strength-wise.
I'd love to see the Executor, among many other underwhelming or outperformed cards see use in gameplay, even if the use is niche i feel the card should at least be very strong in that niche situation to make it stand out and be effective. As such, i'd like to promote the following change.

 
New Ability: Execute
Costs 50 Power. Unit loses 450 HP by activating this ability. Cannot activate if it has less than 450 HP. Unit executes the target enemy, instantly killing it. Can only be cast on enemy units whos current HP is ≤ 50% of its total HP. Can only be cast on ground units with a maximum of 2 orbs and 90 power costs. Cannot be casted on XL Units. Execute could turn the tides of fate for the Executor and bring this card to a new position of use. With the ability to kill an injured enemy up to a point instantly, this could see some great use and make it stand out comparative to its other T1 counterparts. Who knows, this could be one of many things to bring underused and underwhelming cards back into the light of the new sun!
Update: Due to great and considered suggestions by others, the ability concept has been tweaked to cost the unit more health and require less than 50% of the total HP to be left for an execution to be used. This should prevent the ability from being too strong by allowing the executor to instantly destroy a dazed unit, as well as enabling simple spells like eruption, even at U0 to damage the Executor too greatly for it to cast the ability. Additionally, the power cost maximum has been reduced to 90 to prevent units like the Sunderer at U3 from being vulnerable.
Thanks to RadicalX, ImaginaryNumb3r, and Eirias for their wonderful suggestions.
