Il existe un chapitre assez indigeste dans les regles sur les interaction d'effet continus.
Dans ton cas le gatherer eclairci l'interaction
Citation :
If multiple effects modify your hand size, apply them in timestamp order. For example, if you put Spellbook (an artifact that says you have no maximum hand size) onto the battlefield and then put Null Profusion onto the battlefield, your maximum hand size will be two. However, if those permanents entered the battlefield in the opposite order, you would have no maximum hand size.
cela depend donc de l'ordre d'arrivé en jeu
