Back to the idea of 'control is not a viable strategy in Elements', you are giving examples of only spell control. There are many ways to control the opponent with creatures.
One artic squid, (with 3 water pillars) can effectively take 3 creature out of the game (attack and any skills). therefore two of them, and 6 water pillars can take out 6 creatures. One flooding added to this combination (another 3 water pillars) and the opponent is screwed. (Assuming it is a rush, without creature/permanent control)
An elite otyugh with momentum can insta kill all creatures with 5 health or less. Gravity shield blocks all creatures with more than 5 health.
Two flying eternities will completely dominate your opponents hand ( at the cost of 6 time pillars)
An auburn nymph can effectively take 6 creatures out of the game (attacks and skills). The only drawback of this strategy is that they will be all but immune to any damage/health based creature control. But if you have a gravity shield in play, then you can remove one creature per turn (Unless the opponent has gravity pull/reverse time-but then you get rid of these limited cards, when you have unlimited use of auburn nymph) Even better, auburn nymph is not affected by shields
Aflatoxin can completely fill up the opponent's creature area, and with a jade shield, hope, PAd (block 1) shield you can completely stop them using any creatures whatsoever.
Just a couple of strategies to show that control still works in elements
