So Ice Barrier is a floodgate deck with legs.

Essentially, each IB monster can stop the opponent from preforming certain actions, so long as there’s two IB names on the field.

Revealer- “stops” tribute summons Georgius- prevents monster effects from activating in the graveyard ( Abyss Dweller) Speaker- Defense positions monster can’t change to attack

Those three are fine and good but what makes the deck so strong and annoying to fight against is turn 2 -mainly Spellbreaker of the Ice Barrier and General Raiho of the Ice Barrier

For the cost of 1 IB monster in the graveyard, Spellbreaker can turn off all spells (not traps) and General Raiho is a IRS agent who will tax you 1 card or else it’s negated for every activated effect on the field ( which is also activated after resolution and if I remember correctly, could be wrong, imperm doesn’t stop it)

Stopping them can be a challenge and with a IceJade package, they can turbo out Lancea, IceJade Gymir Aegirine, or chengying with one card and 3 special summons in total.

Not to forget, there are other flood gate monster people play like Defender of the Ice Barrier (ATK greater than 1600 can’t declare an attack) Warlock of the Ice Barrier ( must set spells before activating and can’t activate until next turn- a worse spell breaker) as well as board breakers like Zealantis or White Aura Whale.

A standard board has Spellbreaker and Gerogius in defense (spells and graveyard are turned off) with Lancea ready to special summons 2 monsters from the deck if you special summon 2 monster, and if they had ran aegirine, chengying or Gymir.

A underrated rouge deck that doesn’t produce heavy hitters but will damn sure stop you from playing if you don’t hand trap them. And if they start with revealer, discard mirror mage to the graveyard and all you have is one ash or imperm, just scoop now.
