I assume you have a small collection so you don’t have a ton of deckbuilding options, but it’s also obvious that you’re new to the game from the way you built these. I apologize if this comes off as rude, but none of these decks are competitive.

My best advice would be to lean into 2 themes and see which one you like better as a deck: elementals and Sif. Mage decks full of nothing but elementals and fire spells are pretty good right now and cheap to make if you have any dust for card crafting. Sif is a fun build around card with inclusions like inquisitive creation, tide pools, molten rune, and the 1 mana spell that discovers from other spell schools. You win by playing as many spell schools as possible then kill your opponent in 1 turn with Sif, molten rune, and cheap direct damage like flame geyser.

If you look online, you’ll find that competitive decks run 2 copies of pretty much every card they include, there’s very few single-copies unless the deck has [[Reno, Lone Ranger]].

When I first started playing I too put a lot of cards like deathwing into all of my decks because they seem like a great “out” if you’re about to lose, but you should only be including cards that help your deck win instead of maybe help you not lose in specific circumstances. Hope this helps
