I mostly play casual PvP and enjoy the randomness of the interactions a more diverse deck offers. But point taken for competitive deck building.
Regarding units with 6 defense, it just matters that one of the units fulfills this criteria for the Sling to trigger. That was often achieved with 8 such units.
I have 7 cards that grant Aegis. That was usually enough to protect the Slings. But Mistveil in the market could indeed secure Aegis when needed while double-triggering the Sling.
There are good ideas and bad ideas here. But, part of the bad stuff-- no offense intended-- is a fundamental misunderstanding of deckbuilding principles.
"Most decks with Sling of the Chi combo with Belax Suppressor. I wanted to achieve this differently by boosting the attack of units I draw to 6+."
^ You want to be original. Cool, that's fine. But what's missing is the incentive to run units that you have to work harder to combine with Sling. You should find units that become much more powerful once you achieve "the dream" of playing them while Sling is active.
Also, Sling isn't just about 6 attack; it's also about 6 defense/health. That's the draw power part.
Why not find the right cards and run 4 copies each of those cards? Running less than 4 means you have a way to search out what you want, you get diminishing returns when you play too many copies, the card is powerful-but-situational, or the card costs a lot of Power to play. (There is also a certain relic-- hint hint-- that give you a big boost if all your cards are unique).
But, generally speaking, you find the cards that you want and run 4 copies of each one.
Furthermore, you should definitely use the Market to grab Mistveil and give yourself aegis when you need it. (I recommend Delivery for that).
