Best Cobalt Core Artifacts — Tier List

Updated 20 Oct 2026 Source Synthesized from published Cobalt Core guides; rewritten in original wording on 20 October 2026 By

Artifact value depends on your deck. These rankings assume a normal build with no unusual synergy.

Run-defining

Artifacts that give energy, extra plays, or a benefit every single turn. These change what your deck can do.

Strong

Damage and defence multipliers. Good in most decks, better in decks built to use them.

Situational or skip

Narrow effects tied to a card type you do not run. Skip these rather than dilute future offers.

Where to check the data

Frequently asked questions

What is the strongest artifact type?

Anything that adds energy or card plays. More actions per turn compounds faster than raw damage.

Should I always take a boss artifact?

Take the one that fits. A poor fit is worse than none.

Do artifacts stack with upgrades?

Yes, and that combination is where the biggest numbers come from.
