Fast-paced beat-down deck where you can turn 2 swing for 11 or turn 3 swing for 22 with trample.
Win Conditions
There are many paths to victory in the early turns with this deck but they all rely on getting a Colossus Hammer or two on one creature and either hitting them in the face really hard, or flinging them past your opponent's defenses.
Combos
The best combo starters are going to be search for artifacts to get Colossus Hammer (or Shadowspear if necessary), and then cheat the hammer onto your creature with Sigarda's Aid or Magnetic Theft.
I won 2 games very quickly with the combos:
Recovery
If you get shutdown early with creature removal, the best way to reload is to bring out Lurrus of the Dream-Den and a Puresteel Paladin if your artifacts stuck around, or a Stoneforge Mystic if they didn't.
Substitutions
Can be countered by artifact removal or targeted removal getting rid of your big guys if you can't reload fast enough.
Sideboard substitutions of Mask of Avacyn or Lightning Greaves can help against targeted removal, Path to Exile and Pithing Needle can help stop your opponents if they have problematic permanents.
Rest in Peace and Embercleave counter your own companion Lurrus of the Dream-Den but can be useful in certain matchups.
I've lost to an enchantment buff deck that outpaced me on a slow starting had, and a hand mill deck that left me with no creatures and not enough mana for Lurrus of the Dream-Den, so consider adding ways to grab creatures of your choice out of the library.
I am open to any suggestions for improvements, especially in sideboard as I never sideboard anything in between games, it feels like the deck only needs to win by attacking with a big thing early, or it really struggles.
