Epic Cards Battle

I don't think you need to replace yours if someone posts an alternate. I posted mine because I didn't have the cards for yours. I think showing multiple decks to beat a level is good in case someone doesn't have all the cards for one. I have had to find alternatives for several because I still have ...

6.7 can be done with 3 treants and 3 blessing of mother earth. All level 1.

OK, so if you don't have all the fancy cards, how do you get this level? Is it possible without epic or legendary cards? I just want to get past it, not three star it.
Please help. This one has had me frustrated for days.
