Reign of Dragons Upgrade Guide

Lathliss, Dragon Queen

Commander: Lathliss, Dragon Queen

R

Lathliss doubles down on nontoken Dragon entries. Cost reduction and haste let the deck produce Dragons before opponents can answer them.

Where to start upgrading

Deck-specific one-for-one ideas. Check current prices before buying; the budget plans below use live card data when available.

Cut Hit the Mother Lode → Add Terror of the Peaks

Each Dragon that enters alongside Lathliss becomes direct damage, including her 5/5 tokens.

Cut Tyrant's Familiar → Add Wrathful Red Dragon

Makes damage to any of your Dragons punish opponents and works with the token Dragons.

What improves

  • Only $10.06 of the $25.00 budget was needed — the rest of the precon holds up without changes.
  • 15 one-for-one swaps for $10.06 of a $25.00 budget, adding 2 ramp, 2 removal & interaction, 4 support.
  • Average spell mana value drops from 3.73 to 3.53 — the deck plays faster.
  • 15 incoming cards share synergy tags with Lathliss, Dragon Queen.

Remaining weaknesses

  • Only 7 card draw cards after upgrades (most Commander decks want at least 8). A bigger upgrade budget should target this role first.
  • No protection after upgrades (most Commander decks want at least 2). A bigger upgrade budget should target this role first.
  • No win conditions after upgrades (most Commander decks want at least 2). A bigger upgrade budget should target this role first.
  • 2 cards kept (Chaos Warp, Swiftfoot Boots) have no available price, so the plan neither cuts nor values them.

Reign of Dragons · assumes you own the precon; cost covers added cards only.
