Martyr's Soul

If you control any tapped lands as Martyr's Soul enters the battlefield, its last ability doesn't trigger at all. If you control any tapped lands as the ability resolves, you won't put two +1/+1 counters on Martyr's Soul.

If a creature you control has a mana ability with in the cost, activating that ability while casting a spell with convoke will result in the creature being tapped before you pay the spell's costs. You won't be able to tap it again for convoke. Similarly, if you sacrifice a creature to activate a mana ability while casting a spell with convoke, that creature won't be on the battlefield when you pay the spell's costs, so you won't be able to tap it for convoke.
