Cannot attack directly. If this card is banished: You can Special Summon this card, and if you do, this card gains 200 ATK for each of your banished Dinosaur monsters. You can only use this effect of "Giant Rex" once per turn.
No use 3 if you want to use this it’s still a 2000 Attack monster with little draw back
You can use Gold Sarc from the Silent Magician EX Structure Deck to banish Giant Rex staight from the Deck to Special Summon it and it won't return to hand after 2nd Standby Phase since it isn't banished anymore.
Ok so fairy dragon box is actually good?. i mean you can fuse this with gigantes and get 2 monster on field with good atk stats. and both are earth attribute, you can use bastion field skill and maybe make a control earth attribute control or something?
The new box is a support box on its own not so good but use it to complement other boxes and it’s a really good box. But ya this card will definitely see play it’s very easy to spam on the board with stuff like gigantes evil sala and it’s searchable with fossil dig and Golden Sarcophagus which also allows it to summon itself.
