This is a rather troll deck I use against the Hard Trials, I normally use this against Order and Energy.
I use this deck mainly if the enemy has at least one of these cards:
Energy - Tick Bomb
Order - Pushback, Flip
Decay - Searing Shackles
also I avoid using either of my defence deck against trials with Death Cap Berserker as the opponents enchantment.
This deck focuses defending and warding while poking the enemy down to nothing
The scrolls work in the deck as follows.
Waking Stones - Defend for one's life
Resonant Helm / Elan Vital - Heal the waking stone.
Summons - help gets waking stones easier, useless late game unless you somehow lose a waking stone. Then it is an easy fix.
Faith Chains - holds off attacks forcing them to use spells to attack (late game only)
Untainted - Stop the specific cards mentioned at the top from screwing up the formation by giving the waking stones ward.
Crown of Strength / Regeniture / Stag Heart - To increase the structure's health above avalible rush abilities.
Plate Armor - same as crown and regeniture except works against Charge Coil and Ether Pump
Infiltrate - Helps slow creatures so they are unable to destroy something vulnerable or so they dont attack at the same time.
Spell cards- to heal
New Orders - Counter for Rumble since it gets past ward
Decimation - Deal damage to the opponent's idols while beating up their creatures
I hope this deck works as well for you as it has for me, it doesn't work in all circumstances, so choose this deck when you think it is for the best. Have Fun!
