Its a Tuner to summon Virgil and a nice defense wall, making it the best of the new Malebranche monsters.  But its basically just a name, which is all the deck needs to plus.

It's not as good as the original 3 Malebranche monsters but its worth using 3 Rubic (as well as Calcab and Alich) so it increases your chances of making "first turn Dante".

3.5/5

Hello Pojo Fans,
 
Burning Abyss get a Tuner to go with their Synchro monster in the new set. Rubic, Malebranche of the Burning Abyss is the first “Burning Abyss” monster that is a Tuner. Beside the standard “Burning Abyss” monster effects, Rubic cannot be used as a material for a Synchro Summon unless it is a “Burning Abyss” monster.
 
While you still can Special Summon him if you control no spell/traps, the restriction on how he can be used in a Synchro Summon takes away from how good Rubic could have been. There is only one “Burning Abyss” Synchro monster, and though you won't need to do anything special to match levels to make Virgil (all main deck “Burning Abyss” monsters are level 3) the fact that you can only use Rubic to Synchro Summon Virgil is a big downside. Goyo Guardian would be a great target for this card to summon. You likely will always be playing to Synchro Virgil, but Goyo may be needed and you won't have access to him. The option of stacking Rubic with another “Burning Abyss” and making Dante or any other Rank 3 is still there, but Rubic isn't a floater like all the other “Burning Abyss” monsters. You can bring it out with Crane Crane or Tour Guide, bounce with Birdman and go Virgil like that, but that could've been simplified if Rubic didn't have the restriction.
 
Run one right now. There are better Tuner monsters you could tech.

Rubic is perhaps the most flexible in the Burning Abyss archetype. A level 3 DARK/Fiend Tuner monster with 100/2100 ATK/DEF stats, and much like the rest of the bunch, if you control a monster that is not a Burning Abyss monster, destroy this monster. If you control no Spells/Trap cards, you can special summon this card from your hand. And you can only use Rubic for the Synchro summoning of a Burning Abyss monster. You can use it's special summoning effect to get it on the field, then summon another Burning Abyss monster and do what you gotta do from there. Or use Tour Guide to special summon it and have it's effects negated and proceed as you wish. Or, just leave it in in defense mode until you can get what you need, as 2100 DEF is a bit hard to get around. Rubic is a must for the deck type and it's pretty much the swiss knife is some ways for the Burning Abyss deck.
