Anyone else also doesn't get the boost stated underneath? I think it's bugged. Also tested it with numorous cards...
This card gains ATK equal to half the ATK of the Warrior-Type Fusion Material Monster used to Fusion Summon this card
What cards did you use to test them? If the other warrior monster original attack is 0 then you get nothing, if using like light hex sealed fusion, then it won't get anything, if you use 2 neos, then you also get nothing from it, since it's stated on the card text 'except "Elemental Hero Neos"', other than those cases, I see nothing out of ordinary, unless using grandmerge, nothing happens
yeah, i got the same problem. i had tried several times and realized that it will not work if you use Neos Fusion, but you can use Fusion Gate, Fusion Substitute, Polymerization and Vision Fusion, instead. In addition, I love the combo: EH Neos + EH Captain Gold + Neo Space = EH Neos Knight ATK: 4050
