3.3 Miner Mortar

Firstly, use valkyrie as your mini tank and to defend against swarm cards like royal hogs and graveyard. Use arrows as your small spell and against goblin barrel, princess and dart goblin. Use vines to buy some time for your ice wizard or tower and in combination with the miner for more damage. Instead of only using the miner to attack, you can use him to pull the opponent's troops to the tower, if the mortar locks on them, so it'll also be able to hit the tower. Another alternative use for him is to take out buildings. Lastly, he can be used as a mini-tank for defense like valkyrie. Use spear goblins to clear swarm cards like wall breakers, bats and suspicious bush but also as a distraction to kill cards like prince with the help of the cannoneer. Lastly, you can place mortar + tesla instead and use it like xbow + tesla, so you are protected from air troops like bats and minions and from tower chasing cards like hog rider, because it will attack the tesla instead of the mortar, which will kill it, letting the mortar survive. If you do so, use valkyrie and ice wizard as supporting cards like the knight and the archers are being used for in xbow 3.0.
