Ah mono red the joy that is my soul. There are multiple ways you can build mono red for commander depending in what you want to do and how competitive you are. If you’re looking for a quick and easy mono red commander deck, the daretti scrap servant commander 2014 deck is a very good starting point. If you are looking for a competitive, very strong, Purphoros, God of the Forge, is a great aggro commander thay can kill all of your opponents at the same time. This makes yourself a threat and you will be focused but if you can do your thing you can easily out race them. Daretti is a fun commander to build around if you don’t want to buy the pre built one, building a deck centred around artifacts or use Bosh, Iron Golem (yes he’s a mono red commander despite being a colourless artifact creature). Umbrask (red phyrexian preator) is a haste giving machine for any aggressive strategy. Who could also forget the best two tribes for mono red, goblins and dragons. Goblins is a deck that with the right commander (forget his name but he has tap add x goblins where x is the number of goblins you have) you can spawn a horde of 1/1’s to overpower your opponent and dragons well who doesn’t love playing dragons (providing there is a legendary red dragon). Ashling can make for some fun elemental synergies that you could have some really fun with. It’s best to find a commander you want and build and play what you want for the commander environment. There are close to 600 potential commanders so you have to keep yourself alive or kill everyone before they kill you so plan your strategy around that. If you want to have a conversation about magic message me and we can set something up. As the raid team and @Fyrefly21 can say my mind is always on mtg.
Having reread your original post, the deck you have is slow which can work for one shotting someone but not for a full game of mtg against 3 other people. There is enough cheap cards out there making a fun tribal deck should cost maybe 60 bucks at most. Working with 40 lands getting common and uncommon spells and shadowmoor elementals along with a few dollar Rares the deck will let you use ashling’s ability along with making you survive what your opponents are doing. You can easily play the long game with ashling if you can get the cards to survive the early game
If you want a cheap deck to buy check out the budget mtg on YouTube for their purphoros deck. All cards under a dollar is their moto so it won’t be expensive. Lots of cards to buy but they are cheap
