Hydra Themed Deck
T1: land, Arbor Elf;
T2: land, Overgrowth;
T3: land, Gargos, Vicious Watcher and Hydra Broodmaster;
Or
T3: land, Genesis Hydra and another hydra from the top 6 cards;
Or
T3: land, Voracious Hydra as 6/7 removing an opponent's creature or as a 12/13 body;
Or
T3: Polukranos, World Eater and Polukranos Reborn
.
Both Polukranos help early game in case the ramp gets disrupted.
Monstrous Onslaught is usually a one-sided mass removal.
I tested other ramp methods like creature based ramp using the likes of Llanowar Elves with Llanowar Tribe, land search using Search for Tomorrow with Khalni Heart Expedition and all managed to generate around 7 Manas by turn 3 or 4 but they struggled after that point, except for the auras and untap effects approach which generated more mana overall since each new untap effect can essentially work as a mana multiplier with the enchanted lands.
for example, making at least 7 7/7 hydra tokens with Hydra Broodmaster monstrous ability happened way more often than anticipated with auras plus untap effects while other approaches started to struggle past the 3rd token while trying to keep a consistent list.
Usually the more the ramp distances itself from creatures towards land based ramp, the harder it gets to be interacted with and disrupted. The auras, creatures and kiora method seems a fine mid ground
all hydras give some form of advantage.
sideboard are mostly permanents so you can fetch what's needed with Genesis Hydra
Utopia Sprawl could be in place of Wolfwillow Haven for faster mana, it's slightly more expensive though.
*
Nykthos, Shrine to Nyx, Lotus Field and Castle Garenbrig and Titan type of ramp using Amulet of Vigor + Simic Growth Chamber should be tested
