Can give a high attack increase if used with a high attack monster.
Can use face down monster's attack to give to your other monster.
Takes the base/original attack of the used monster instead of current attack.
Piranha Army + Master of Oz = 5,000 attack that will deal 10,000 damage, which is enough to get the highest attack bonus.
You can use Riryoku to increase your main monster's attack and use Gift of the Martyr by taking the reduced monster's attack to still give the original attack. example: Use Riryoku by taking Blue-Eyes White Dragon's attack and give to Piranha Army, then use Gift of the Martyr by using BEWD and giving it to Piranha, which will result in Piranha with 4500 + 800 = 5400 and will deal double that damage if it can attack directly.
this cards description should be updated or something cause in game im using this and noticed two things ....or it could be considered as one thing......it only works for a monsters original attack.....so in my 2 uses of the card i had maju garzett at 5800 attack and cu chu at 5000 and when i used the card:1. it didi not let me sacrifics maju to boost cu chu and 2. when i sacrificed cu chu it only gave me the added 500 original attack
I think this because it reads the monsters atk once it is in the grave therefore atk printed on card original atk.
I think with maju it sees it as zero so it does not let you or it cant add a question mark as an atk.
The reason this card only add original attack but the text didnt say anything about it because when this card resolve, the monster you send already in the graveyard so it lost all the buff which mean its ATK equal its original attack.
So it not confusing at all
