Eluge's power and toughness are each equal to the number of Islands you control.
Whenever Eluge enters or attacks, put a flood counter on target land. It's an Island in addition to its other types for as long as it has a flood counter on it.
The first instant or sorcery spell you cast each turn costs (or ) less to cast for each land you control with a flood counter on it.
Eluge is a mono-blue voltron/spellslinger hybrid that grows with your Islands while flooding lands to ramp out cheap instants and sorceries. You drop Eluge turn 4-5, attack to add flood counters every turn, and either swing for lethal as a giant unblockable beater or chain massive spells at deep discounts. Land-doubling and Island-matters payoffs accelerate the snowball.
Self-contained threat that's both a wincon and a cost-reducer in one card
Flood counters convert any land into an Island, juicing landfall and Island-count synergies
Mono-blue gives access to the format's best counterspells, card draw, and protection
Cheap spells let you hold up interaction while still developing the board
Power/toughness depends on Islands, so board wipes and removal reset your investment hard
Heavy reliance on the commander makes repeated removal taxing via the command tax
Mono-blue struggles with enchantment/artifact removal and lacks efficient creature removal
Slow to close if Eluge is answered and you've over-committed to flooding lands
Extra turns mean extra attacks, flood counters, and lethal Eluge swings.
Add land-doubling and ramp like Vorinclex, Voice of Hunger and Nyxbloom Ancient plus extra-turn spells to multiply attacks and flood triggers. Lean into evasion and protection (Whispersilk Cloak, Aqueous Form, Heroic Intervention-style blue protection like Tale's End) so a single removal spell doesn't reset you. Top-end the spell suite with cost-multiplied bombs and a tutor package to find your discount enablers consistently.
