Instants
Instants have the surprise factor together with Hylda's ability. Leaving open mana to then do a ton of stuff never felt better. + options to recover from the graveyard with Lier and/or Snapcaster for example. Downside is that these are one-time effects, and limited value without hylda on the board.
- - Blustersquall: Stormy enough to make the cut, plus the instant mass tap effect for all opponents is not something we can skip.
- - You See a Guard Approach: Protection for Hylda + the ability to do an instant one mana tap effect. Versatility win.
- - Plunge into Winter: Tap, scry, draw in one cheap instant spell. Can cast it early (before Hylda) without worry due to the scry + card draw.
- - Crippling Chill: Tap + card draw
- - Frost Breath: Tap and keep tapped
- - Succumb to the Cold: Tap and keep tapped
- - Cryptic Command: Star of the show.
- - Icy Blast: Versatile tapper, + we should always have a 4/4 body to trigger Ferocious
Enchantments
Enchantments lose a lot of the benefits instants have, but can have more continuous impact. I opt for only a few due to their synergy/secondary or permanent effects. I would refrain from using enchantments for tap effects that do not have any other strong benefit. Currently no way as well to recover these from the graveyard, and due to the limited number of enchantments not something I want to pursue. Added the 2 cheap permanent tap enchantments since sometimes you just want to keep things tapped.
- - Winter's Rest: flavor and permanent tap for cheap
- - Bitter Chill: flavor, permanent tap and with a draw option.
- - Solitary Sanctuary: Taps + engine on its own to take advantage of tap effects to grow creatures
- - Time of Ice: Saves mana on next turn tap for tap effects + mass bounce you can time for.
- - Opposition: Do whatever you want, as long as you have mana to pay for Hylda's ability. The most broken enchantment with Hylda.
Sorceries
Same as enchantment, do not have the benefit of instants and are usually more one-time effects compared to Enchantments. So any sorcery needs to have a massive effect for it to be included:
- - Sleep: Having the second ability trigger even on already tapped creatures is massive, plus with a 4CMC cost it is cheap enough to still enable Hylda's ability and swing for 1 or 2 rounds.
- - Bond of Discipline: We do need some lifegain, although when casting this spell it might also just be a win instead.
Artifacts
I prefer these artifacts above creatures with similar tap effects due to flavor, haste and to diversify tap effects, even though creatures with tap effects can benefit from Hylda's +1/+1 counters. Repetitive cheap tap effects at instant speed (1 at sorcery). Currently no way as well to recover these from the graveyard. At some point might want to include Academy Ruins if the mana base can handle it. Or to replace bastion.
- - Greatsword of Tyr: Note: even if it is only during combat, the equip cost is cheap enough to trigger it continuously and does not cost any mana once equiped (frees up mana for Hylda's ability)
- - Hylda's Crown of Winter: obvious inclusion for flavor, tap and card draw.
- - Scepter of Dominance: included for flavor and cheap tap effect.
- - Icebind Pillar: obvious inclusion for flavor and recurring cheap tap.
Creatures
Creatures will be the main enablers of repetitive tap effects + can be boosted with counters.
- - Dreamshackle Geist: cheap, repetitive tap, + flyer. And versatility to keep tapped.
- - Elvish Mariner: infinite hylda triggers as long as you have mana.
- - Icewrought Sentry: the second ability is key here as it can get out of hand when having numerous/mass tap effects in place.
- - Court Street Denizen: triggers on each 4/4 created. Great synergy. Court/royalty flavor.
- - Lossarnach Captain: provides bodies to go wide and get +1/+1 counters, repetitive tap. Great synergy.
- - Tempest Caller: mass tap effects we can flicker if we opt to invest more into that route.
- - Thassa, Deep-Dwelling: Free flicker since we have multiple creatures with ETB effects (looking at you illithid harvester) + repetitive tap effect. Fits perfectly.
- - Sharae of Numbing Depths: enjoy your card draw on each turn.
- - Timin, Youthful Geist: triggers on each combat step. Massive.
- - Illithid Harvester: Being able to turn any creature (or all creatures we want up-side down is amazing. Especially since it can be done repetively with some flicker effects.
- - Gadwick, the Wizened: nice to cast early or late!
