Compulsory Evacuation Device plus Synchro monster equals?

The OCG definitely has a bigger cardpool, specifically with the available synchro monsters. Competitive decks in the TCG include Gaia Knight, The Force of Earth on their Extra Decks for the simple reason that it has a huge ATK of 2600, despite having zero monster effects and that's in an easy level 6 synchro. One of the better alternatives for it, if not replace it, is Brionac, Dragon of the Ice Barrier, part of the Ice Boundary archetype, which is not yet introduced in the TCG.

Brionac, Dragon of the Ice Barrier

For those non-Japanese empowered people, this card reads as:
Sea Serpent/Synchro/Effect
1 Tuner + 1 or more non-Tuner monsters
Discard any number of cards to the Graveyard. Then, return cards from the field to its owner's hand equal to the number of cards discarded.

Although this card does not boast heavy ATK and DEF stats, this card can prove to save your hide on certain duels as it has the effect to bounce any card on the Field back to its owner hand. Perfect targets for this card are Gladiator Beast Heraklinos and Dark Armed Dragon and almost every synchro monster existing today, as this card bounces them back in the Extra Deck. Don't forget that his effect is an ignition effect and you can use it as many times as you can and as you want, provided that you have the cards in your hand to discard for its cost. Just don't expect this card to be effective against certain cards like the Monarchs, for example, as you will help give your opponent an extra devastating monster effect, sometimes to destroy even more of your cards, including this card.

This alone makes this card worthy to put in every Extra Deck when the time comes that this card is released in the TCG.
