Using Common Towers is a good option to be with you in league 1 as in fact fiends are in league 1 are strong but you have to deal with them and common towers is enough especially when it is upgraded to higher level with speed or with damage with mana.
So you can use common towers and also using epic towers and rare in the market is not bad as it have special abilities but at the end if you don't have enough DEC so you could use these common towers to face fiends and eliminate them in the battle and also you could use spells that are common.
Jack Joke is one of common and strong towers that can be used in the battle and have a speed of 0.9 so it could be used to attack fiends and if it is upgraded so it would be good for attacking any type of fiends in the field and at the end we could use some spells with this towers so it is better than or even like rare and epic towers.
Charnel Pit is one of towers that could be used with 120 Mana and could be used for a battle that has a common fiends in league 1 and it has a fire inteval of 0.6 as one of fastest towers to be used in the battle and with its speed it could deal with fiends from any type like bloodling and terror mite and also it could damage blood queen.
Gloom Owl is also a good physical damage that could be used in any level and it is one of towers that we have started the game with and in this case we are able to use a speed of 1 Sec and that could be fast one like the two others and with this formation you could have a good speed that could face fast fiends like bloodlings.
