You have no maximum hand size.
Sonic Booster — Whenever Nyssa of Traken attacks, sacrifice any number of artifacts. When you sacrifice one or more artifacts this way, tap up to that many target creatures and draw that many cards.
Doctor's companion (You can have two commanders if the other is the Doctor.)
Nyssa is a mono-blue card-advantage engine: build a board of cheap, recurring artifacts (Treasures, Clues, Food, artifact tokens), then attack to sacrifice them for a huge draw and to tap down attackers/blockers. You use the overflowing card advantage to fuel control, counters, and an artifact-fueled finisher while the no-maximum-hand-size clause lets you hoard answers. Pair her with a Doctor partner to add a second color or extra synergy, but she runs fine mono-U as a draw-go control deck.
Add fast mana and token-tripling pieces (Sol Ring, Mana Crypt, Academy Manufactor) plus reliable artifact-token engines so every attack sacrifices a stack. Lean into infinite-token or untap combos with outlets to convert Nyssa's draws into a kill, and choose a Doctor partner that adds removal or a closing threat. Round out with strong blue interaction (Cyclonic Rift, Force of Will, Fierce Guardianship) to protect the engine.
