Take a look at this picture and what do you notice? Yes, my right hand tower is getting completely destroyed by the trainer. However, that is not the point of the picture. The other side shows a Balloon getting pushed along by a Baby Dragon, believe it or not this is a strategy in Clash Royale.
The whole point of this strategy is speed. There are some troops that might be too slow to your liking. Slow troops can take way too long to get to defenses making you lose out on potential damage. In spite of this, you CAN speed them up a bit, without a Rage Spell.
To speed these troops up, all you need to do is put a fast troop behind it! It is as simple as this. In the picture at the beginning, it shows a Baby Dragon, which is a fast troops pushing a Balloon, which is a medium speed troop. Combined, it increase the speed of the balloon, but slightly decreases the dragon.
This is not only limited to flying units but also to ground units. You can push a Golem, Giant, or even a Valkyrie with just a few goblins are a hog rider. This can especially catch your opponent off guard with this increased speed and give you a few easy hits.
There is no huge strategy that goes with this. This is more of a tip that allows one to get better. You can't really set up a deck that revolves around this, but try to apply this strategy to the decks you currently use. For more tips on Clash Royale click here.
