"Working together" Mechanic

After seeing various mechanincs in other games that work on a specific archetype of cards helping one another, I have been wondering what it would require to create a feasable set similar  in TP.

My inspiration comes from:

• "Sliver-Type" Creatures in Magic the Gathering (All Slivers Gain X)
• "Survivor-Type" Monsters in Duel Monsters (All survior cards gain X)

These cards are usually weaker when played alone but gain strength when played together.

I was thinking of creating a number of cards with POW values lower than the averages for their costs, for example the [Tension 6] Cards will be around POW 4 or 5, and the originals will be around POW 3 or 4 depending on their effect. This is a risky strategy where good deck-building and playing "X Turns ahead" will be important.

The archetype will have a symbol similar to the "Shine" and "Rush" cards.
Potential names include: "Link", "Team" and "Plus". (I'll Just call it link for now.)

The Ruling will be:
[link] All other cards with [Link] gain X while this card is in the Battle-Pile.

I have decided to write some example cards which will depict how a deck like this will be played.

[Card 1]
Colourless 4, [LINK]: This card gains: "This card can be any colour but only one at a time"

[Card 2]
Yellow 5, [Link], [Tension 5]: This card gains: "Gain 1 Life"

[Card 3]
Purple 4, [Link]: This card gains "Remove 1 card from your opponent's Battle-Pile."

[Card 4]
Red 4, [Link]: This card gains "If this card is POW 4 or less, it gains +1POW

[Card 5]
Blue 7 , [Tension 9] [Link]: This card gains: "Add 2 cards to your battle-pile.

[Card 6]
Colourless 4, [Link]: This card is now colourless

[Card 7]
Red 5, [Tension 4] [Link]: Deal 1 Damage to your opponent.

[Card 8]
Blue 3, [Block: Non-blue 7 or 9 ], [Link]: Your opponent cannot play a card that is the same colour as the one you played last.

The "Link" cards will have the following rulings:

1. "Link" effects happen AFTER the effect printed on the card.
2. All "Link" Abilities Stack.

The thing is with this rule is that I'm afraid that the effects will go down too smoothly; I am looking to invent cards that "smash open" decks that are based on archetypes in either a 2nd or 3rd set.
