TypicalTimmy on Clockwork Hydra's Wording; "This isn't …

3 years ago

Every so often we come across a card who's wording is a bit ambiguous. This is where rules and errata come into play. However, sometimes in rare occasions these rules are not officially stated, and we are left with interpretations.

This is one of those instances.

Clockwork Hydra is simple; Enters with 4x +1/+1 counters and whenever he attacks or blocks you make him weaker by removing one of them. It's the second part of this trigger which I take problem with;

"If you do, Clockwork Hydra deals 1 damage to target creature or player."

Normally, when a card gives you the option to do something it says "you may". Clockwork Hydra does not say this, therefore it implies you MUST remove a counter. But the wording "If you do (...)" implies the opposite; You have the CHOICE to do so.

So my question is this: When he attacks or blocks, do we absolutely need to remove a +1/+1 counter, which makes the "If you do (...)" part a grammatical oversight, or do we have the option to do so, and if we do not than no damage is dealt by the trigger?

(This is what years of D&D does to you, by the way. Rules as Written [ROW] vs Rules as Implied [ROI].)

Let me start by adding to your problem by saying that with Umbral Mantle or Staff of Domination you can go infinite pretty easily. Your deck looks like it functions significantly better with yeva or omnath in play. Without them you get to untap your lands on other people's turns but you might not be able to take advantage of that. Just something to be mindful of. Anyways here are some cuts hope this helps:

Nature's Will: My selvala list (i can send you a link if you want but the focus is less on value and more on just achieving an infinite combo quickly) empties its hands pretty quickly and i think you might do the same. After the first trigger or too all this will do is tap down their lands and unless you are playing in a counterspell heavy meta, they can just cast their spells in response to the trigger.

Bow of Nylea: has lot's of abilities but overall not sure if it pulls enough weight.

Savage Punch as far as removal goes, I like Duplicant a lot better here. It's also easier to tutor for

Avoid Fate: Vines of Vastwood is generally better especially since the +4 power is relavent.

Stream of Life unless you have lifegain synergies or are in a very VERY aggressive meta straight up life gain spells usually arent great. If the reason you need to cast this is due to your opponents creatures, you would rather draw a card to deal with them rather than a card that buys a turn for you to draw that card.

Predator's Rapport: it's a lot more efficient but the same holds true for this one.

Clockwork Hydra as much as i love this card ((and believe me i do) it's honestly not the best hydra out there. It's pretty slow and inefficient.

Phyrexian Hydra if you get in one hit with him then it dies it will be pretty hard to deal anymore poison damage and did not lower his life total, your main path to victory.

Hooded Hydra you'd much rather have other hydras here. he's better in a token deck rather than one who wants the big body.

Kusari-Gama cool effect but you need to make cuts somewhere and i think you can do without this one.

Looking at your sideboard there are a few there i'd cut too but Archetype of Endurance and Courser of Kruphix should try to get in the main deck if possible

Bristling Hydra with no other ways to make energy, this isnt worth it

Nissa, Nature's Artisan a lot slower than the other nissas in the deck and doesnt do as much.

Seedtime Only good if your opponents are playing a lot of blue instants. Not all blue decks play counters so this could be a dead card you can't cast. If your meta is heavy blue i'd consider it, otherwise i'd pass.

Sprouting Phytohydra Other than being a hydra, this doesnt do much here. 0 power for five mana does not help selvala make mana

Been thinking about a few other cards with Horibo synergy. Mainly colourless cards that target creatures:


Shizo, Death's Storehouse. Produces mana symbol b. With Horibo, mana symbol bmana symbol tto kill target commander.

Urborg. Produces mana symbol b. With Horibo mana symbol tto kill.

Cabal Pit. Lifeloss, but an additional removal spell with Horobi at Threshold.

Maze of Ith\Mystifying Maze, go from defensive to tappable kills.

Tower of the Magistrate. Useful protection into a kill.


Echo Chamber. Copy their creature and kill it at the same time. Opponent chooses the creature.

Helm of Chatzuk. With Horibo mana symbol 1mana symbol t to kill target creature. No real utility without.

Baton of Morale\Sacred Armory. With Horobi mana symbol 2 to kill target creature. No real utility without.

Thran Forge. Higher cost, better utility.

Power Matrix. Without Horobi powers up one of our or opponents creatures. With Horobi becomes a mana symbol t Murder.

Soldevi Golem. mana symbol 4 5/3 that kills a creature when it untaps

Serrated Arrows. mana symbol 4 for 3 x murders.

Sentinel. Kills pretty much anything it can block with Horobi out.

Crenellated Wall. Blocker. mana symbol t to kill a creature with Horobi.

Contagion Engine. Potential wrath and Planeswalker boost.

Clockwork Hydra. 4/4 for mana symbol 5. With Horobi takes a creature with it when it attacks or blocks.

Belbe's Armor. With Horobi, mana symbol 0mana symbol t kill. Without, boost a creature on defense.

Barl's Cage. mana symbol 4cmc cost, but a useful effect in Horobi's absence.

Grim Poppet. mana symbol 7cmc for 3 x Murder at instant speed and a potential 4/4 blocker.

Erratic Portal. Tappable Murder with the ability to bounce our own creatures back to recur ETB effects.
