Adric, Mathematical Genius
The Commander
Guide
Gameplan
Adric copies your best activated and triggered abilities, doubling value engines like draw triggers, mana abilities, and ETB/attack triggers. As a Doctor's companion he's almost always paired with a blue-inclusive Doctor partner, so you build around stacking and replaying triggers while protecting Adric, then convert that snowballing card and resource advantage into a combo or overwhelming board. His Ultimate Sacrifice doubles as interaction by countering a key activated or triggered ability.
Strengths
- Doubles the value of any activated/triggered ability you control, turning good engines into game-warping ones
- Built-in interaction: can counter an opponent's crucial activated or triggered ability by sacrificing
- Doctor's companion gives access to a second commander, widening colors and strategies
- Cheap to cast at 2 mana, so he comes down early and recovers quickly
- Repeatable copy effect with new targets enables flexible value and combos
Weaknesses
- Mono-blue on his own lacks ramp and removal depth; leans heavily on the paired Doctor
- Copy ability costs
and a tap, which is mana-intensive and slow each turn
- Vulnerable to removal—losing Adric stalls the whole engine
- Needs a critical mass of strong abilities to be worth the activation cost
- Telegraphs combos, inviting interaction and being targeted first
Key Cards
- The Tenth Doctor — A premier blue Doctor partner whose suspend-and-cheat-time triggers Adric loves to copy.
- The Thirteenth Doctor — Strong blue companion whose time counter and value triggers scale with Adric's copies.
- Isochron Scepter — Imprinting a cheap instant gives a repeatable activated ability that Adric can copy for free value.
- Thousand-Year Storm — Spell-cast triggers copied by Adric explode card advantage and combo potential.
- Aetherflux Reservoir — Copying the life-gain trigger accelerates toward the 50-life laser kill.
- Strionic Resonator — Stacks with Adric to copy triggered abilities multiple times for runaway value.
Upgrade Path
Pick a high-impact blue Doctor partner that generates repeatable triggers (suspend, time counters, or ETB value) so Adric always has targets. Add cheap protection (Swiftfoot Boots, Mother of Runes-style effects, counterspells) and fast mana (Sol Ring, Mana Crypt, signets) to power the activation each turn. Tighten toward a dedicated combo finish—Isochron Scepter loops, Aetherflux Reservoir, or extra-turn chains—rather than diffuse value.
