If this is the wrong place I’m sorry and I will delete this post.

Me and my play group wanted to do a modern tournament just within our group so we are each building a deck. Typically we don’t really play with any specific rule set/legality BUT this is modern legal cards only with the stipulation being we have to build the deck with the cards we already own. My main worry is only have 20 lands but after looking over a lot of hammertime lists I think this is okay. It certainly won’t be winning any tournaments but do y’all think it will be okay for our kitchen table tournament?

If not what should I cut?

Nimbus Maze x2

Glacial Fortress x2

Plains x5

Islands x5

Urza’s Saga x2

Springleaf Drum x4

The Reality Chip x1

Shadow spear x1

Memnite x2

Ornithopter x2

Giver of runes x2

Counterspell x2

Open the armory x2

Esper Sentinel x2

Thoughtcast x2

Blacksmith skill x2

Loxodon Warhammer x3

Colossus Hammer x4

Sigarda’s Aid x4

Kor Duelist x4

Puresteel Paladin x4

Blighted Agent x3

I know it’s not amazing but it’s what I had from decks I don’t play and cards in binders will it hold up?

Edit: 16 lands 20 sources of mana with the spring leaf drums my apologies that wasn’t very clear
