As the second triggered ability resolves, you must cast the card if able. You must do so even if it requires targets and the only legal targets are ones that you really don’t want to target. Timing permissions based on the card’s type are ignored.

Exiling a card with suspend isn’t casting that card. This action doesn’t use the stack and can’t be responded to.

If a card with no mana cost is given an alternative cost equal to its mana cost (by Snapcaster Mage, for example), that cost cannot be paid and the card cannot be cast this way.

If the first triggered ability of suspend (the one that removes time counters) is countered, no time counter is removed. The ability will trigger again at the beginning of the card’s owner’s next upkeep.

If you cast a card “without paying its mana cost,” such as with suspend, you can’t choose to cast it for any alternative costs. You can, however, pay additional costs. If the card has any mandatory additional costs, you must pay those to cast the card.

Suspend is a keyword that represents three abilities. The first is a static ability that allows you to exile the card from your hand with the specified number of time counters (the number before the dash) on it by paying its suspend cost (listed after the dash). The second is a triggered ability that removes a time counter from the suspended card at the beginning of each of your upkeeps. The third is a triggered ability that causes you to cast the card when the last time counter is removed. If you cast a creature spell this way, it gains haste until you lose control of that creature (or, in rare cases, you lose control of the creature spell while it’s on the stack).

The converted mana cost of a spell cast without paying its mana cost is determined by its mana cost, even though that cost wasn’t paid.

Mox Tantalite has no mana cost. You can’t cast it unless an effect (such as that of suspend) allows you to cast it for an alternative cost or without paying its mana cost. Its converted mana cost is 0.
