Tried playing Conjurers calling on the new Yogg (in Arena), it destroyed Yogg but did not replace with anything. It should have given me 2 new Yoggs, since Titans still count as minions and it is the only 15-cost minion.
The only way to generate a Titan is putting it in your deck and copying/resurecting it (yours or your opponent’s).
You can’t discover one and can’t generate one from purely random effects.
Almost like Colossals. You can discover them, but you can’t generate them from purely random summon effects.
