To a point. However, regardless of deck-building skill, the draw is still random, so your hand is still random. Most CCG's (including Hearthstone) limit the number of duplicates of any card you can include in your deck. Hearthstone's mana system also adds some extra restriction to deckbuilding as you need to maintain a certain distribution of cards of certain cost, or you'll end up with a hand full of cards you can't afford to cast in the early game, or a bunch of ineffective but cheap cards in the late game.
So, in answer to your question: yes. BUT deck building is both a factor of AND a contibutor to the inherent luck-based aspects of the game. Deck building translates to card draws which translates to your hand, whose usefulness is dependent upon your mana reserves, which feeds right back into deck building. In Magic, mana reserves are a part of the deck design (and the only type of card NOT restricted to a small number of duplicates). This allows you to build more designed strategy into your deck's functionality and separate yourself more from the factors of luck. Hearthstone's "have another mana every turn" removes all of that in favor of a vastly simpler, more level-playing-field approach. Neither's wrong, but they both absolutely come with trade-offs. Magic's system requires you to be more familiar with the flow of turn and game and have a little more foresight, while Hearthstone leaves you more immediately dependent upon what you happen to get in your hand.

Not really. However, it's an illustration of one of the biggest "simplifying factors" of taking a CCG digital. Most card games have complicated and very, very carefully chosen text explaining (in terms of game rules) how the card works. Often, a card will see text revisions to remove unintended loopholes allowed by text wording. So, in a lot of cases, this kind of use of a card will be ruled out by that wording. BUT, other times it's left alone. Some very unusual strategies can hinge on "helping" your opponent or buffing their cards.
For example: My opponent has a
Greater Basilisk out. It's Deathtouch ability means any of MY creatures that attack it will die, even if they also kill the Basilisk. Not appealing, especially considering that the Basilisk's 5 toughness means it might even take more than one of my own creatures to deal enough damage to finish it off. But if I happen to have
one of these, whose ability is "Target creature deals damage to itself equal to its power" I can make the Basilisk damage itself. The Basilisk only has 3 power (damage) though, and with 5 toughness (health) Kiku's ability won't finish the Basilisk off. I could use
this guy, though to add 2 power to the Basilisk, then use Kiku to make it kill itself. I've just cleaned up an irritating creature without having to sacrifice any of my own, partly by buffing the very card I was trying to kill.
Of course if I had
Dark Triumph instead of Agend of Skauku, this whole strategy wouldn't work, since Dark Triumph specifically only targets my own cards.
Hearthstone doesn't have the wording issue, as the functionality of the cards is all built into the digital game. It means card texts can be more "natural" and easier to understand despite potentially complex functionality under the surface. It also assures correct use of cards (there's a reason games like Magic have Judges at tournaments--it can often be difficult to interpret rules in complex scenarios). So it cleans things up a lot (the Hearthstone M.O.) while removing, perhaps, a little depth from ultra-strategic use of certain rules or abilities or wordings.

Also when or if Hearthstone gets competitive, could people boost their rank by winning in this manner?
You could, but really no more than match fixing is possible in any other online competitive game. And the manner of win doesn't factor into rank. If you defeat an opponent with 9 billion damage, it's no different than defeating them with the 4 you actually needed to deal to barely win. A win is a win, and a loss is a loss. If you can make it happen within the game's rules without your opponent intentionally "throwing" the game, it's fair.
